　　CCTV News:A few days ago, the Publicity and Education Center of the Ministry of Environmental Protection and the Beijing Environmental Protection Publicity Center jointly exposed the "Top Ten Smog Rumors of 2016". Let’s see which rumors once made you believe!

　　Rumor: Beijing smog in macro lens?

　　A video of Beijing smog shot with a 4000 lumen light macro lens is shocking. In the video, some small particles are floating around, which is really scary to watch. Many netizens have said that masks that have been suspected before must be worn this time, and some netizens commented that "this kind of air will kill people." The video has been forwarded by nearly ten thousand people.

　　truth Fog droplets and fine particles that form smog are invisible to the naked eye, so it is necessary to use microscope instruments. What the video sees is just dust.

　　Proverbs 2 Automobile exhaust is 10 times cleaner than air, and the contribution of motor vehicles to smog is not so great.

　　In a video from a car website, on a heavily polluted day, a person wearing a gas mask extended the air quality detector to the exhaust pipe of a car, and the reading of PM2.5 dropped from nearly 500 to 48. It is concluded that automobile exhaust is 10 times cleaner than the air in foggy days.

　　truth Most of the contribution of automobile exhaust to pm2.5 is indirectly generated. The exhaust contains substances such as nitrogen oxides and volatile organic compounds (VOCs), which are gases and will not be reflected in the air quality tester for measuring PM2.5.. However, these gases are both "raw materials" and "catalysts" for PM2.5 production. Among the local pollution sources in Beijing, the contribution of pollutants emitted by motor vehicles to PM2.5 is 31.1%, which accounts for 40% in non-heating season. Organic matters, nitrates, sulfates and ammonium salts generated by secondary conversion account for 70% of PM2.5.

　　Proverbs 3: A red warning was issued because of the presence of ammonium sulfate in the smog?

　　In mid-December 2016, Huanghuai and other places in North China suffered from a wide range of smog weather. Under the shadow of persistent smog, some rumors began to breed on the Internet. A message widely circulated on the Internet said, "Internally, this smog mainly contains ammonium sulfate, which was not the level of red warning, but it only reached this level because of the existence of ammonium sulfate. Remind the children not to go out. The purifier at home is turned on for a long time. Drink more water. It turned out that ammonium sulfate exceeded the standard in London, and many people died without protection. "

△ On December 16, 2016, Beijing launched a red warning of heavy pollution.

　　truth According to the "Emergency Plan for Heavy Air Pollution in Beijing", the red warning is to predict serious pollution for four consecutive days or more, of which two days will reach serious pollution; Or the single-day air quality index (AQI) reaches 500. Ammonium sulfate is not the standard for issuing a red warning.

　　The paper "From London Fog to China Haze: Persistent Sulfate Formation from London Fog to Chinese Haze" published in the Proceedings of the National Academy of Sciences in the United States in late November pointed out that in China, agricultural nitrogen fertilizer and industrial emissions produce a large amount of ammonia pollution, and alkaline ammonia promotes the reaction process of sulfur dioxide and nitrogen oxides, forming a large amount of ammonium sulfate, but also neutralizes the acidic environment, making China smog neutral in pH value.

　　Although the neutral pH of smog in China doesn’t mean that smog in China is harmless, it doesn’t have as strong acute toxicity as acidic fog in London. The acute toxicity of ammonium sulfate is not great, and the deadly culprit of London fog is high concentration of sulfur dioxide.

　　Rumor has it that the four wind power stations and shelterbelts block the smog caused by strong winds?

　　Some people think that a large number of wind power stations have been built in Inner Mongolia to steal the strong wind in Beijing, and the three-north shelterbelt attenuates the wind in the north, resulting in smog that cannot be blown away.

　　truth The wind can recover when it hits an obstacle, and local wind power generation or local shelter forest will not affect the downstream wind power far away. The fundamental reason for the formation of fog and haze is that the ground pollutants hit the static condition of the atmosphere. At present, no scientific research shows that there is a causal relationship between wind farms or shelterbelts and the formation of smog.

　　Proverbs five smog is because of "nuclear pollution".

　　It is said that large-scale uranium and coal resources have been found underground in Erdos, Inner Mongolia. Through burning, uranium in coal enters the air, which is the reason for the large-scale smog in China at present.

　　truth The main influencing factor of smog is meteorological conditions. Uranium itself is a very heavy element, which is not easy to be oxidized and will not become dust; Moreover, the power plant will carry out dust removal, desulfurization and denitrification on the emissions, even if they really exist, they should also be left in the combustion residue, and the amount entering the air is very small.

　　Rumor 6 "coal to gas" aggravates air pollution in Beijing?

　　An article entitled "Smoke emission from natural gas boilers is an important reason for aggravating the haze weather in Beijing" said that smoke emission from natural gas boilers is the main source of "rich water vapor" in Beijing and an "accomplice" to aggravate the haze air. The article says that the development of natural gas in Beijing is a double-edged sword, which has the clean energy side, the negative influence of water vapor emission and the pollution of nitrogen oxides.

　　truth Wang Zifa, a researcher at the Institute of Atmospheric Physics, Chinese Academy of Sciences, said that according to the current natural gas consumption in China, the gaseous water produced by burning natural gas is about 300 million tons every year. If all of it is converted into liquid water (in fact, it is impossible to convert all of it into liquid water), it will be spread evenly in the eastern part of the country where the population is concentrated (estimated area is about 3.6 million square kilometers), and the thickness of liquid water is less than 0.1 mm/year, accounting for only one hundred thousand of the precipitable water in the atmosphere, with little impact. Therefore, "changing coal to gas" will not significantly increase the humidity in Beijing’s atmosphere, and it is not the main source of "rich water vapor" in Beijing.

　　Professor Feng Yinchang of Nankai University said that no matter burning coal, gas or oil, nitrogen oxides will be emitted. Whether "changing coal to gas" will lead to the increase of nitrogen oxides mainly depends on the combustion mode and quality of coal before changing gas and the combustion technology adopted after changing gas. If low-nitrogen combustion technology is adopted, the emission of nitrogen oxides will be reduced. Denitrification started later than desulfurization in China, and the concentration of nitrogen oxides in the atmospheric environment has not decreased as significantly as that of sulfur dioxide in recent years. The increase of nitrogen oxide concentration may cause secondary pollution, but it is controllable. Moreover, the causes and mechanism of pollution are very complicated. It is not scientific to say that the pollution of particulate matter is still serious because the concentration of nitrogen oxides has not decreased significantly.

　　Proverbs 7: Beijing’s air quality is gradually deteriorating?

　　Some people think that the smog is frequent now, and the air quality in Beijing is not improving but deteriorating.

△ On December 30, 2016, Beijing was shrouded in smog.

　　truth According to the monitoring data of the Ministry of Environmental Protection, as of December 27, 2016, the average concentration of PM2.5 in Beijing in 2016 was 72 μ g/m3, down 10.0% year-on-year (down 8 μ g/m3) and down 20% compared with 2013 (down 18 μ g/m3). The assessment report "The Course of Air Pollution Control in Beijing: 1998-2013" issued by the United Nations Environment Programme in 2016 shows that from 1998 to 2013, the average annual concentrations of sulfur dioxide (SO2), nitrogen dioxide (NO2) and inhalable particulate matter (PM10) in Beijing decreased significantly by 78%, 24% and 43% respectively, and the air quality in Beijing has been improved in the past 15 years. In addition, the monitoring data of international organizations such as NASA in the United States also support the trend of continuous improvement of air quality in Beijing.

　　Proverbs 8 smog can only wait for the wind, and emergency measures for heavy pollution are useless.

　　There is a view that the smog in Beijing can only wait for the wind, and the measures that took so much effort to implement during the period of heavy pollution did not play a role in driving away the smog.

△ On December 23, 2016, Beijing ushered in the blue sky after smog.

　　truth The function of heavy pollution emergency is to reduce pollutant discharge and pollutant accumulation as much as possible through certain emergency emission reduction measures, so as to protect public health to the maximum extent. According to professional calculations, during the Red Police this year, PM2.5 was reduced by about 23% and other pollutants were reduced by about 30% on average compared with no measures. Haze is caused by pollutants discharged by human production and life exceeding the environmental capacity under certain meteorological conditions. Only by reducing the emission intensity of pollutants through corresponding control measures can the air pollution problem be fundamentally solved, which requires a long-term process.

　　Proverb 9 Beijing is seriously polluted by smog, and the air contains antibiotic-resistant bacteria.

　　On November 23, 2016, four scholars from the Research Center for Antibiotic Resistance of the University of Gothenburg in Sweden mentioned in their research that "the antibiotic resistance gene was detected from the smog in Beijing". Subsequently, some domestic WeChat WeChat official account published the title "Breathing Pain! Drug-resistant bacteria are found in smog in Beijing and other places, and more than 60 kinds of drug-resistant bacteria in smog in Beijing will lead to drug failure. On November 24, 2016, some media released a news titled "Drug-resistant bacteria were found in Beijing smog, and" the last antibiotic of mankind "could do nothing about it". The news was reprinted and commented by a large number of media and self-media on the 25th.

　　truth The Beijing Municipal Health Planning Commission responded that the drug resistance and pathogenicity of bacteria are completely different concepts, and the increase of drug resistance does not mean the enhancement of pathogenicity. Many experts at home and abroad said that bacterial drug resistance has nothing to do with smog, smog does not produce drug-resistant genes, and smog has no necessary causal relationship with drug-resistant bacteria. The acquisition of bacterial drug resistance is caused by evolutionary selection and induced selection of antibiotics, not by smog. The hazard factors in smog are mainly chemical pollutants, which have adverse health effects on respiratory system and cardiovascular system, and the health risks caused by microorganisms are very small.

　　Proverbs 10 smog blocks alveoli? The incidence of lung cancer in Beijing is much higher than that in the whole country, showing a younger trend, and air pollution is the culprit.

　　There is no doubt that smog affects health, but some opinions circulating on the Internet are varied: the incidence of lung cancer in Beijing is much higher than that in the whole country, showing a younger trend, and air pollution is the culprit? Can 80 PM2.5 particles block an alveolus? Will smog make fresh lungs turn black for six days? Smoking smog for a day may lead to hemiplegia? Can smog lead to infertility? Smog makes people lose their lives for five and a half years?

　　truth In response to these questions, Academician Zhong Nanshan once said that "many data about smog carcinogenesis are taken out of context, exaggerated or tampered with".

　　In fact, from 2003 to 2012, excluding the aging factor, the average annual growth rate of lung cancer in Beijing was 1.2%. In 2011, the age-standardized incidence rate of lung cancer in Beijing was 23.53/100,000, while the latest standardized incidence rate of lung cancer in China was 25.34/100,000. It can be seen that the incidence rate of lung cancer in Beijing was slightly lower than the national average. The median age of lung cancer in Beijing in 2011 was 71 years old, which increased by 2 years compared with the median age of 69 years in 2002. It can be seen that the incidence of lung cancer in Beijing is not younger. Others, such as "80 PM2.5 particles can block an alveoli?" Will smog make fresh lungs turn black for six days? Smoking smog for a day may lead to hemiplegia? Can smog lead to infertility? Smog makes people lose their lives for five and a half years? " Such rumors, without scientific basis, have been confirmed as rumors by relevant authorities.

　　Pluto, once "Laojiu", has now been "reduced" to a dwarf planet.

　　Our reporter Gao Bo

　　Not long ago, two foreign astronomers put forward a bold idea: the ninth planet in the solar system, which is "hidden from time to time", is likely to be an original black hole.

　　There is a black hole in the solar system that controls distant celestial bodies? Some experts said that this is an interesting hypothesis, but it is difficult to confirm or falsify with the current observation ability.

　　The vacant throne, there are new contenders.

　　More than a decade ago, who was the ninth planet was clearly written in the textbook. In 1930, clyde tombaugh discovered PLUTO, equating it with Uranus and Neptune, giving it the magnificent Greek name "Prouteau", and the nine planets in the solar system became a kind of common sense knowledge.

　　However, scientists later realized that Pluto seems to be "far from enough to see" in the outer space of the solar system. Since 1992, some distant ice-stone structures have been discovered one after another, and their volume is similar to Pluto. In 2005, it was discovered that the planet Eris was 27% more massive than Pluto! Pluto can be counted as the ninth largest, and it’s unreasonable that Venus doesn’t rank tenth.

　　Astronomers made a decisive decision, and the 26th International Astronomical Union held in August, 2006 passed a resolution: Pluto was classified as a dwarf planet and removed from the nine planets in the solar system. Prouteau abdicated tragically and became an asteroid 134340.

　　But the throne of the ninth planet is not so easy to cancel. In recent five years, some new discoveries have led people to speculate that there may be a real "P9" (the ninth largest planet) in the solar system.

　　On September 24th, another newcomer joined the battle for the throne — — ArXiv.org posted a paper, and Jakub Scholtz of Durham University in Britain and James Unwin of the University of Illinois in the United States put forward a bold idea: the ninth planet in the solar system may be an original black hole.

　　Strange orbit, pointing to the hidden "P9"

　　Around 2014, astronomers discovered some celestial bodies in the Kuiper Belt (the area near the ecliptic plane outside Neptune’s orbit). When the orbit is far from the sun, it can reach hundreds of astronomical units (one astronomical unit is the distance between the sun and the earth). At first, this was explained as the gravitational scattering effect of Neptune. But soon, the conjecture of the new ninth planet was put forward.

　　In 2016, michael brown of California Institute of Technology and his colleagues discovered that six celestial bodies in the Kuiper Belt have strange orbits, and their perihelions all point in the same direction. It’s like six clocks that turn at different speeds, but the hands all point in the same direction. If Neptune was behind the scenes, their directions would have been scattered and not so concentrated.

　　Moreover, when the six celestial bodies are closest to the sun, the distance is more than 40 astronomical units, and the Neptune hypothesis is not easy to explain.

　　Michael brown and his colleagues calculated that the probability of "big guys pointing to accidental coincidence" is 0.007%— — It is more realistic to believe that there is a "big guy who has not yet appeared".

　　Zhou Liyong, an astronomer and professor at Nanjing University, said in an interview with Science and Technology Daily that many people opposed the existence of "P9" at first. With the continuous discovery in recent years, the statistical significance of confirming the existence of the ninth largest planet has gradually increased.

　　Although "P9" has not been observed, some people have speculated its parameters through computer simulation: it is 200 to 800 astronomical units away from the sun, and its mass is 5-mdash that of the earth; Ten times, it takes 30,000 years to circle the sun … …

　　It is not necessarily the earth that wanders, but it may also be a black hole.

　　Astronomers used to believe that the possibility of a new planet outside Neptune is very small, because the material in this area is too thin, and it takes too long to grow a big planet. But what if the solar system "plundered" a ready-made planet from the vast universe? This possibility is worth considering.

　　"In fact, there may be many wandering planets in the universe, just like in the movie ‘ Wandering earth ’ Same. " Xie Jiwei, an astronomer who studies extrasolar planets and an associate professor at Nanjing University, told the Science and Technology Daily reporter that one way to find extrasolar planets is called gravitational microlensing method, which is to capture the weak deformation of images — — The light is distorted by the mass of a celestial body along the way to find clues about the existence of exoplanets. In this way, we have observed many "clues", indicating that there are many "tramps" who are unorganized and undisciplined in the unknown darkness.

　　In the suspected area of "P9", the gravitational anomaly was observed in the optical gravitational lens experiment (OGLE). At least six gravitational microlensing events indicate the gravity anomaly in this area, suggesting the existence of a free-floating celestial body with a mass range of 5-mdash; Between 15 earth masses. The conjecture of "P9" is therefore encouraged.

　　The new paper by Schultz and Unwin speculates that this celestial body may not be a rogue planets, but a wandering black hole. It was drawn into the group by the solar system, which disturbed the orbit of the outer celestial bodies.

　　Generally speaking, black holes observed by astronomers are gathered after the death and collapse of stars. The original black hole that exists in the theoretical assumption is another matter. Hawking made a great contribution to this concept: it was a "cultural relic" that came into being shortly after BIGBANG.

　　The universe before the Big Bang was called the primordial universe by astronomers. The explosion of the original universe was uneven, and the energy density in the local space was too high. Without collapsing, it was compressed into points with infinite mass and surrounding black holes. This kind of black hole varies in size, and it may be as small as a particle. The general primary black hole is similar in mass to the common asteroids in the solar system.

　　These black holes then drift around the universe. Some are dissipated by Hawking radiation and melted like ice; Others absorb substances and grow, and survive to this day.

　　Schultz and Unwin pointed out that the abnormal orbits of celestial bodies outside Neptune, as well as some gravitational events, can be explained by the original black hole whose mass is several times that of the earth; An original black hole may be captured by the solar system and become the ninth planet; They proved that the possibility of this capture is worth considering.

　　Strict assumptions, there are still many voices of opposition.

　　"The idea of this paper is still very rigorous and standardized, not a guess." Xie Jiwei said, "but the author also said that this is only a possibility. Introducing the concept of black hole may be interesting and strange to everyone. But the next step is still impossible. Moreover, whether there is the ninth largest planet is still a problem. "

　　Schultz and Unwin said that if "P9" is an original black hole, it may pass through the peripheral "halo" — — The positive and negative electrons in the outer layer of a black hole annihilate the light to determine its existence. However, a planetary scientist told the Science and Technology Daily reporter that such observation is difficult to achieve because the black hole is small and uncertain in its location.

　　"I personally don’t like the idea of the original black hole." An expert engaged in planetary research told the Science and Technology Daily reporter, "It feels almost mystical — — Can explain some phenomena, but basically never see it. "

　　"The discoverer of Kuiper objects, David Jewitt, didn’t even believe in ‘ The ninth planet ’ The existence of. " The expert said that David Jewett said in a TV interview that he didn’t think "P9" existed. He believes that the black hole hypothesis reveals that scientists are eager to make "major discoveries". But this theory is far from the stage of verification.

　　An important reason for different opinions is that it is still difficult to observe celestial bodies outside Neptune at the current level of human technology. Although humans have observed thousands of extrasolar planets.

　　"I don’t know the true face of Lushan Mountain, but I am only in this mountain." Xie Jiwei said, "Observing exoplanets basically infers the situation of planets indirectly by observing the Ling Xing effect or Doppler effect of star spectra. The planets in the solar system can be directly observed. The brightness of a planet is inversely proportional to its distance from the sun. Celestial bodies that are too far away will receive weak light and reflect weaker light. "

　　The periphery is so vast and the celestial bodies are so dim. Beyond hundreds of astronomical units, it is still unknown.

　　Xie Jiwei said: "Many celestial bodies on the edge of the solar system were seen through the Hubble telescope; After the Weber telescope works, our observation level will improve a little. "

I drive a Camry (parameter picture) twin engine, and there are three shortcomings that are unacceptable, and it is really expensive to change the battery. I advise people who want to buy a hybrid car to think twice, otherwise it will be too late to regret it!

The automobile industry is experiencing a great change that has never happened in a hundred years, and it has become an inevitable trend to develop new energy vehicles.

Plug-in hybrid vehicles and pure electric vehicles are the main models in the future, while hybrid electric vehicles will be eliminated in the future!

This is the real reason why Corolla twin-engine, Camry twin-engine, CR-V and other hybrid vehicles can’t be on the "green card"!

However, at present, Toyota and Honda-based hybrid electric vehicles have achieved high sales, and many consumers are waiting to see and want to buy a hybrid electric vehicle.

So is the current hybrid car worth buying? What are the shortcomings?

Next, I will analyze the advantages and disadvantages of the hybrid car and how much it costs to replace the battery, hoping to give some valuable information to readers who want to buy a hybrid car.

What’s the difference between Toyota THS, Honda i-MMD and BYD DM-i? Did DM-i learn from Honda i-MMD?

We want to know whether the hybrid car is worth buying. First, we need to understand the working principle of the hybrid car, so as to understand the advantages and disadvantages of the hybrid car!

At present, Toyota THS and Honda i-MMD hybrid systems are the main hybrid vehicles. Although both of them are hybrid systems, their working principles are obviously different.

The working principles of Honda i-MMD and BYD DM-i are more similar, so Honda CR-V has two hybrid models, one is a hybrid electric vehicle, and the other is a plug-in hybrid vehicle.

Honda’s i-MMD oil-electric hybrid uses clutches to realize three driving modes.

The first pure electric modeWhen the engine does not work, the clutch of the power separation device is disconnected, the vehicle is directly driven by the motor, and the power battery provides the power source. At this time, the working principle is the same as that of a pure electric vehicle.

The second hybrid modeThe vehicle is still directly driven by the driving motor, and the engine works normally. At this time, the power clutch is disconnected, and the engine is only responsible for driving the motor to generate electricity, and does not directly participate in the driving.

At this time, the working mode is more like an extended-range electric vehicle, and the driving principle is the same as that of an extended-range electric vehicle in Li ONE, so the engine always runs at the highest efficiency and the fuel economy is very high.

The third engine direct drive modeThe engine is working, the power clutch is closed, and the driver controls the power output of the engine through the throttle. At this time, the working mode is the same as that of the fuel vehicle.

When the vehicle needs to overtake and speed up, the motor intervenes to drive, and the auxiliary engine drives the vehicle together. At this time, the vehicle has the strongest power.

The above three driving modes are basically consistent with the working principle of BYD DM-i. Some people think that DM-I borrowed the working principle of i-MMD, but as early as 2008, BYD introduced F3DM, which is the world’s first mass-produced dual-mode vehicle.

The working principle of BYD F3DM is not the same as that of the familiar Tang DM, but the same as that of the Song Plus DM-I. As for why it was not accepted by the market at that time, the main reason was that the engine carried by the F3DM was too poor.

The DM engine is equipped with a 1.0L three-cylinder engine, and its power output is not strong. In the hybrid mode, the power output is insufficient, which makes it impossible to play the advantages of the hybrid mode, so it was eliminated by the market.

In 2012, Honda released the i-MMD hybrid technology, and in 2013, it officially launched the production model, so it was not DM-i that borrowed from i-MMD.

Toyota THS has developed into THS II, which is much better than the previous generation and can be divided into two driving modes.

The first pure electric modeThe engine does not participate in the work and will not start, and the vehicle is driven entirely by the motor, which is the first difference from Honda i-MMD.

However, the pure electric mode of Toyota THS II has a disadvantage, taking Camry twin engines as an example.

Because the battery is only 1.3kwh, it can only be turned on when the power is sufficient, and the pure electric mode can only travel about 2KM, and the speed cannot exceed 50km/h, otherwise it will directly exit the pure electric mode.

It can be said that the pure electric mode of Camry dual-engine is relatively small, but the application scenarios are still relatively rich. For example, the pure electric mode can be enabled when moving cars in short distances, congested roads and queuing, which can avoid the engine idling for a long time.

On the one hand, it can avoid carbon deposition caused by long idle speed of the engine, on the other hand, the engine stops working to achieve the purpose of saving fuel.

The second hybrid mode, due to the working principle of Toyota THS II, is divided into two working states in hybrid mode.

The first working stateDuring normal driving, when the Toyota THS II exits the pure electric mode, the vehicle directly enters the hybrid mode, and the engine and motor drive the vehicle at the same time.

When the power output by the engine is greater than the driving force required by the vehicle, the engine will drive the generator to charge the battery.

The second working stateWhen speeding up overtaking, long-distance climbing and high-speed driving, the engine and motor will still drive the vehicle together, but the engine will use all the power to drive the vehicle and the generator will stop charging the battery.

The power battery also uses all the electricity for motor-driven vehicles, at which time the vehicle has the strongest power. Because Toyota THS II has no engine direct drive mode, this is the second difference from Honda i-MMD.

The first disadvantage, the characteristics of the hybrid working mode of oil and electricity, can’t be green, can’t be exempted from purchase tax, and the price is expensive, saving fuel but not saving money.

Whether Toyota’s THS II or Honda’s i-MMD, the energy for driving vehicles in pure electric mode still comes from fuel.

The cruising range of pure electricity is too short, and the motor is only an auxiliary function. The main driving mode is the engine.

Therefore, hybrid electric vehicles are not new energy vehicles, so they can’t get a green license, and they can’t enjoy the same exemption from purchase tax as plug-in hybrid vehicles.

Take Camry twin engines as an example. The starting price is 219,800 yuan, 40,000 yuan more than the fuel version of the entry-level Camry, and 20,000 yuan more than the fuel version of the Camry with the same configuration.

Imagine that the hybrid of oil and electricity does save fuel, but can it save fuel and money?

I’ll work out an account for you.

With the same configuration, the fuel consumption of the fuel version Camry is 5.7L； per 100 kilometers; The average fuel consumption of Camry twin engines is 4.1L per 100 kilometers.

• The dual-engine version saves 1.6L fuel consumption per 100 kilometers compared with the fuel version.
• No.95 gasoline is 7.51 yuan per liter.

Camry dual engine saves 12.016 yuan in fuel per 100 kilometers compared with the fuel version of Camry. Driving 100 kilometers can save fuel in 12 yuan. Is it worth buying a hybrid car?

If the extra 20,000 yuan for purchasing the dual-engine version is used as fuel money,

20 thousand yuan can buy 95 # gasoline 150200L L.

The dual-engine version saves 1.6L fuel consumption per 100 kilometers compared with the fuel version.

Then Camry twin engines need to travel 93,875 kilometers to save the extra 20,000 yuan.

However, more than 90,000 kilometers, in addition to operating vehicles, basically few car owners can save fuel and money.

If a private car travels 10,000 kilometers a year, it will take at least 9 years to save money on fuel return, so it is said that hybrid electric vehicles save fuel but not money.

Moreover, it is not the same as plug-in hybrid cars. Although plug-in hybrid cars are also fuel-efficient and do not save money, they can get a green card without purchase tax, which is suitable for car owners.

Therefore, the first unacceptable disadvantage of the hybrid electric vehicle is that it saves fuel and does not save money. With the working principle similar to that of the plug-in hybrid vehicle, it can’t be a green card!

The second disadvantage is that the engine is noisy.

The engine noise of hybrid electric vehicle is very loud, which I felt on Camry twin engines, but it is not disturbing all the time, mainly in two cases, the engine noise will be very obvious.

In the first case, the cold car starts.

When the battery is fed, the cold car starts again. At this time, the engine noise of Camry dual-engine will be very loud, and the engine noise can be felt in the whole underground garage. Sometimes it will be caused by traffic jams for a long time, which may be because the engine water temperature is low.

When the car is cold, the engine can’t reach the best state, but it needs to drive the motor to charge the battery, which leads to the noise of the engine increasing under the combination of these two States.

In the second case, when driving at high speed, the battery is strongly charged.

When the Camry twin engines are driving on the highway, the engine cannot directly drive the vehicle due to the hybrid characteristics of Toyota THS II, so the battery must be charged.

Because the vehicle runs at high speed, it requires high power. At this time, it is necessary to drive both the vehicle and the motor to charge the battery, which leads to insufficient engine power.

In order to complete these two working conditions at the same time, the engine can only increase the speed, because the self-priming engine can only obtain the best power output at high speed.

Therefore, when driving at high speed and the battery is strongly charged, the noise of the engine will become very large. If it is sensitive to noise, it will affect the driving experience.

The third disadvantage is that the battery capacity is too small, and the power connection will shake.

As mentioned earlier, the battery capacity of the Camry twin-engine is only 1.3kwh, so it can only travel at a low speed of about 2km, which means that the Camry twin-engine basically travels in hybrid mode.

However, when switching from pure electricity to hybrid mode, sometimes there will be jitter, sometimes very small, sometimes very large, and sometimes not at all.

This is related to the small battery capacity. When the battery feed is switched to the hybrid mode, the engine needs to drive the vehicle and the engine to generate electricity at the same time, so the engine power is insufficient, and the power connection jitter appears.

If the power is switched when the battery is fully charged, and the engine and the battery drive the vehicle at the same time, there will be no jitter.

Therefore, the jitter caused by too small a battery may be unavoidable. This shortcoming is actually good, but it is somewhat unacceptable for car owners who pursue perfection.

Replacing the battery is expensive, so drive carefully.

Toyota and Honda’s hybrid electric system can be said to be very mature, and they all adopt "shallow charging and shallow discharging" to extend the battery life.

As long as the battery capacity of Toyota THS system is lower than 60%, it will stop discharging directly, while that of Honda is 55%.

This has both advantages and disadvantages. The advantage is that the battery can always be kept at more than 50%, which can increase the number of battery cycles and prolong the battery life.

The disadvantage is that the battery capacity of the hybrid electric vehicle is very small, and it is lightly charged and discharged every time, which makes it impossible to switch the power output mode for a long distance, which may cause the body to shake.

Due to the protection methods adopted by Toyota and Honda for the power battery, under normal use, the battery will basically not decay to the point where it cannot be used normally or be damaged.

Moreover, Toyota guarantees the battery for 8 years or 200,000 kilometers, and Honda guarantees the battery for 10 years or 200,000 kilometers, so the owner does not have to worry about battery damage, and it is expensive to replace the battery.

However, if the battery is damaged by the owner, it is not cheap to replace a battery.

Theoretically, taking the Camry dual engine as an example, the battery capacity is only 1.3kwh. At present, the power battery is 1,300 yuan /kwh, and it is 1,300 yuan to change a battery, plus the working hours are up to 3,000 yuan.

In fact, according to the maintenance cost of replacing the power battery exposed by the owner, it is obvious that it cost 23,848 yuan to replace the battery.

Therefore, it is not cheap to replace the battery in a hybrid electric vehicle, but as long as you drive normally, you basically don’t have to worry about the cost of replacing the battery.

Advantages of hybrid gasoline-electric vehicle

Although I mentioned the disadvantages of hybrid electric vehicles, its advantages cannot be ignored.

1. Whether driving at high speed or in traffic jam, the fuel consumption is relatively stable, and the fuel consumption per 100 kilometers is basically about 5L, which is very suitable for car owners who often run long distances.

2. A tank of oil can run more than 1000 kilometers, so you don’t have to worry about mileage anxiety, and you don’t have to refuel frequently. In today’s fast pace of life, the time saved is money.

3. No matter under any working conditions, the power of the hybrid electric vehicle can come at any time, the power output is better than that of the fuel vehicle, and the power ride comfort and driving experience are incomparable to that of the fuel vehicle.

The extra cost of buying a hybrid electric car may not be able to save fuel and money, but the driving experience is great!

Write it at the end

Hybrid cars are worth buying, but not for everyone.

If you don’t use cars frequently, don’t run at high speed, and just commute to work, then a fuel car is enough.

If there are requirements for power, endurance and long-distance driving, then a hybrid electric vehicle is worth buying.

If you buy a hybrid electric car just to save money, then I advise you to think twice. Actually, it doesn’t save money. If you buy it rashly, it’s too late to regret it!

At present, some unscrupulous operators sell fake and shoddy drugs by packaging them as "magic doctors" and "magic medicines", fooling the elderly into buying them and illegally seeking huge profits.In this regard, the China Consumers Association reminds elderly consumers to improve their awareness of risk prevention and self-protection ability.

Drugs without an approval number are counterfeit. Don’t buy drugs through informal channels.

First, we should buy drugs through regular channels such as hospitals and pharmacies, and carefully check the approval number of drugs. Except for Chinese herbal medicines and Chinese herbal pieces that are not subject to examination and approval management, drugs listed in China shall be approved by the drug supervision and administration department of the State Council, and can be listed only after obtaining the drug registration certificate and approval number, so as to ensure the safety, effectiveness and quality controllability of drugs. Consumers should try to choose hospitals, clinics, pharmacies and other formal places (including e-commerce platforms) that hold the Drug Business License and Business License to buy drugs, and carefully check the approval number (national medicine quasi-font number) and expiration date of drugs. Consumers can make inquiries and verification on the website of National Medical Products Administration. Consumers should never buy drugs that have no approval number or can’t find the information of national medicine quasi-brand name on National Medical Products Administration website, so as to avoid being infringed by counterfeit drugs.

In May, 2021, Wenzhou Market Supervision Bureau of Zhejiang Province announced a typical case of "Iron Fist" action in the field of people’s livelihood in the city recently, one of which was "Longwan District Market Supervision Bureau investigated and dealt with Yang Mobin’s suspected case of producing and selling counterfeit drugs". On February 25th, 2021, law enforcement officers of Yongxing Institute of Longwan District Market Supervision Bureau inspected Yang Mobin’s residence according to the report clues, and found 8 bottles of "new gout specific medicine", and the outer packaging was marked with "Function indication: acute and chronic gout, this medicine has the effects of expelling wind and removing dampness, dispelling cold and relieving pain & HELIP; …” Words such as, in line with the definition of drug, but the product has not obtained the drug approval document. The above drugs were tested by Wenzhou Food and Drug Inspection Science Research Institute, and dexamethasone was detected. Yang Mobin’s act of selling the above-mentioned counterfeit drugs is suspected of violating the provisions of Article 141 of the Criminal Law, which constitutes the crime of selling counterfeit drugs. At present, the case has been transferred to Longwan Branch of Wenzhou Public Security Bureau for investigation according to law.

Foods with significant medical effects are likely to be illegally added with drugs.Products are harmful to health.

Food is not medicine, and it has no effect on treating diseases. For some "foods" that claim to be able to treat diseases, they are either false propaganda or drugs are probably illegally added. Long-term consumption of such "food" will bring great health risks to consumers.

Among the typical cases of the fourth batch of 2021 cases in the field of people’s livelihood investigated and dealt with by the General Administration of Market Supervision on August 24th, there was a case in which the Market Supervision Bureau of Jiyuan City, Henan Province investigated and dealt with Huang and others selling illegally added drugs and food. On July 5, 2021, Jiyuan Municipal Market Supervision Bureau received complaints from consumers, saying that the pollen yam tablet candy it bought in Huangmou had a very good hypoglycemic effect after taking it, but at the same time there were a series of adverse reactions. After inspection, glibenclamide was detected in the product. Glibenclamide is a prescription western medicine with obvious hypoglycemic effect. Because of the obvious side effects, long-term large-scale use will cause hypoglycemia and kidney disease, and even lead to death, so the drug can only be used by specific people and needs to be taken under the guidance of a doctor. The behavior of the parties concerned is suspected of violating the provisions of Article 38 of the Food Safety Law "No drugs shall be added to the food produced and operated" and the provisions of Article 144 of the Criminal Law, which constitutes toxic and harmful food in production and sales. At present, the case has been transferred to the public security organs.

"imperial doctor"The "magic medicine" is a false advertisement. Don’t lose your health in pursuit of it.

In order to obtain economic benefits, some unscrupulous operators publish false and illegal advertisements involving traditional Chinese medicine, and induce consumers to buy and use them through false or exaggerated curative effects. This behavior not only affects the healthy and orderly development of Chinese medicine, but also adversely affects the life, health and safety of consumers.

In the fifth batch of typical cases of investigating and handling "Tiequan" in 2021 people’s livelihood cases announced by the General Administration of Market Supervision on September 29, there was a case that "Qilihe District Market Supervision Bureau of Lanzhou City, Gansu Province investigated and dealt with the false advertising case published by Gansu Zhuoyuantang Internet Hospital Co., Ltd. according to law". On March 17, 2021, the Qilihe District Market Supervision Bureau conducted an on-site inspection of Meilin County Chinese Medicine Clinic of Gansu Zhuoyuantang Internet Hospital Co., Ltd. according to the clues reported, and found a large number of "Product Introduction — Ninger Formula, Product Introduction — The advertising materials of the product "Huofei Prescription" are printed with the words "ancient prescription and ancient method for collecting and processing drugs". After investigation, the company published "Lanzhou Zhuoyuantang Chinese Medicine Museum — — The article "Pioneer of online diagnosis and treatment" promotes "the annual number of medical visits is more than 100,000"; The first online consultation Internet hospital in Lanzhou — 　 — The article "Zhuoyuantang Chinese Medicine Hospital" promotes "specially invited Chinese medicine academicians, Chinese medicine masters and outstanding Chinese medicine experts inside and outside the province" and other contents. At the same time,The company’s customer service staff publicized "guarantee never to recur" to patients through online consultation; We use the secret recipe for more than 200 years ","the average cure rate is over 95% "and" to ensure that it will never recur; There are hundreds of thousands of rehabilitation cases and so on. The company’s advertising is inconsistent with the facts and seriously misleads the public. The above-mentioned behavior of the parties violates the relevant provisions of Articles 16 and 28 of the Advertising Law and is an illegal act of publishing false advertisements. Qilihe District Market Supervision Bureau imposed an administrative penalty of 800,000 yuan on the parties according to law.

　　China Weather Network News "Others laugh at me for wearing thick clothes, and I laugh at others for being frozen." After a cold wave at the beginning of November, the cold air was uninterrupted, and many places in China experienced a night of winter. Today (November 10th), a new strong cold air has been delivered, with a sharp drop in temperature and a wide range of influence. It will go all the way south to northern South China, and 30 provincial-level cities will hit a new low in the second half of this year. Coincides with the "Double Eleven" period, it may not only be a shopping cart, but also a bone-chilling cold. China Weather Network launched a national early warning map of down jackets to see where it will experience bone-chilling cold, and it is necessary to wrap a long and thick down jacket.

　　National down jacket warning map released, two-thirds of the country needs down jacket protection.

　　At the beginning of November, affected by the cold wave, many places experienced a big reversal of cold and warm, taking off cool summer clothes and turning out warm equipment such as long pants and coats. However, the cooling is far from over, and a new cold air has been delivered. From now until the beginning of next week, a large-scale temperature bottoming contest will be held in the central and eastern regions of China, and 30 provincial-level cities will set a new low in the second half of this year.

　　According to Zhang Juan, a meteorologist of China Weather Network, this strong cold air process will boost the winter process in North China, Huanghuai and other places, and the impact will also go deep into the south, bringing about a big temperature dive, and two-thirds of the country needs down jackets to protect itself.

　　According to the national early warning map of down jackets launched by China Weather Network, three days from now, Northeast China, Inner Mongolia and other places will experience the freezing cold, and the areas that need to wear down jackets will go south with the main body of cold air and reach the northern part of South China.

　　On November 10th, the main body of cold air mainly affects friends in the north, Qinghai, most of Tibet, the northeast and the central and eastern Inner Mongolia. The lowest temperature can be reduced to -20℃ to -15℃, and it will be frozen in minutes when going out, and the temperature is below freezing point during the day. It is necessary to wrap a long thick down jacket in cold weather all day. Most of Xinjiang, North China, Huanghuai, Shaanxi-Gansu-Ningxia and other places will also experience the cold below freezing point in the morning and evening. For example, the lowest temperature in Beijing dropped to -3℃ on the morning of the 11th, which will set a new low in the second half of this year, and it is also necessary to keep warm and wind-resistant down jackets.

　　On November 11th, with the cold air heading south, the highest temperature in most parts of the south of the Yangtze River will drop to around 15℃. Although it is not as chilly as the north, the temperature will also hit a new low in the second half of this year. Coupled with the rain, the wet and cold feeling is obvious, and it is not enough to wear a coat. You can apply for a down vest.

　　On November 12, cold air continued to penetrate south, and the area where down jackets were needed was extended to the south of the Yangtze River. Like Changsha, the highest temperature on the 12th will drop to 9℃, so it’s time to put on a down vest. As the temperature drops in eastern Inner Mongolia, northwestern Shanxi, northwestern Shaanxi and some places in Xinjiang, it will be frozen all day, so it is necessary to wrap a long thick down jacket when going out.

　　After the cold wave crosses Nanling Mountain, its influence will be obviously weakened, and its influence on most parts of South China is a spent force. The cooling range is limited, and the maximum temperature will drop from 30℃ to about 20℃. The body feels slightly cool, long sleeves and coats are enough, and down jackets will continue to press the bottom of the box.

　　How to choose down jackets these three misunderstandings need to be avoided.

　　The footsteps of winter continue to press south, and the weather is getting colder and colder. Down jacket is essential as the ultimate warm artifact. China Weather Network has identified three misunderstandings in the selection of down jackets. Have you been recruited?

　　The quality of down jacket can be identified from the aspects of filler, bulkiness, softness and fabric, which can refer to the four-step method. At first glance, the filler can be identified. Check the label to find out the type and content of the filler. A down jacket with less than 50% cashmere can’t be called. Press twice to test the bulkiness. By pressing down the down jacket to test the bulkiness, the down jacket with high bulkiness has enough air layer to strengthen the warmth. Three touches, experience softness. Feel the softness of the down jacket by touching it. The down jacket with high softness has lower down stalk content and higher down feather content. Four beats, beat the down jacket to test whether the fabric is hairy.

　　The strong cold air process coincides with the "Double Eleven", and many small partners’ goods have already flown on the road, and the rain and snow weather brought by cold air may affect the progress of logistics and distribution. Snowfall will occur in Xinjiang, Qinghai and other places, and logistics may be blocked; There will also be a large-scale precipitation and logistics slowdown in the south. Vehicles are easy to slip in snowfall weather, which increases the hidden danger of traffic accidents and thus affects the timeliness of logistics distribution. Express logistics enterprises need to pay special attention to weather forecast and early warning and other relevant information, make emergency plans for sudden weather changes, strengthen after-sales service links such as logistics distribution and cargo transshipment, and minimize the impact of disastrous weather on logistics and transportation.

　　China Weather Network reminds us that this year’s "Double Eleven" express is under great pressure, and the delivery task of the courier brother is even more arduous due to the cold weather and inconvenient transportation caused by rainy and snowy days. If there is a short delay in delivery, everyone can give more tolerance and understanding. Finally, I wish everyone’s packages can arrive in time without being affected by the weather.

China. com, December 16-Omicron mutant spreads quickly, is highly contagious and spreads invisibly. However, with the variation of the virus, the vast majority of infected people are mild or asymptomatic in clinical features. For people with mild and asymptomatic infections, people with no basic diseases or with stable basic diseases, they can take care of themselves at home. According to the "Guidelines for Home Treatment of Covid-19 Infected Persons" (hereinafter referred to as "Guidelines") issued by the State Council in response to the joint prevention and control mechanism of novel coronavirus epidemic, as well as the relevant tips from local CDC and medical experts, China. com combed the following 30 questions and answers, covering knowledge points such as protection, medication, medical treatment for key populations, vaccination, etc., to help the general public do a good job in personal protection and home treatment.

1. What should I pay attention to when I am infected with COVID-19?

The "Guide" clarifies that home therapists should take temperature measurement and self-health monitoring once every morning and evening. If symptoms such as fever and cough appear, they can take symptomatic treatment or oral medication. When necessary, you can also contact the medical staff of primary health care institutions or consult relevant medical institutions through Internet medical forms. Asymptomatic people don’t need medication. When taking medicine, home therapists should take it according to the drug instructions to avoid blind use of antibacterial drugs.

The Guide suggests that when you are at home, you should open doors and windows regularly every day to keep indoor air circulation. If you don’t have natural ventilation conditions, you can use exhaust fans for mechanical ventilation. Do a good job in ventilation and disinfection of shared areas such as toilets and bathrooms. Wash hands or disinfect hands when preparing food, defecating before and after meals, taking off masks, etc. Cover your nose and mouth with a tissue when coughing or sneezing, or cover your nose and mouth with the inside of your elbow, and throw the used tissue into the trash can. Do not share daily necessities with other family members. Tableware should be cleaned and disinfected after use. The surfaces of articles that may be contacted by home therapists and the towels, clothes and quilts they use should be cleaned and disinfected in time, and the personal belongings of infected persons should be placed separately.If the family shares the bathroom, the home treatment staff should disinfect it every time they use it; If family therapists use a separate bathroom, they can be disinfected once a day. Used paper towels, masks, disposable gloves and other household garbage are put into plastic bags and placed in special trash cans. Articles contaminated by saliva, sputum, etc. shall be disinfected at any time.

4. When can I end the home treatment?

The Guide makes it clear that if the symptoms of home-based therapists are obviously improved or have no obvious symptoms, the self-test antigen is negative, and the Ct value of Covid-19 nucleic acid detection for two consecutive times is ≥35 (the interval between the two tests is more than 24 hours), home-based therapy can be ended, and normal life and going out can be resumed.

5. What should I pay attention to when I go to the hospital?

Shen Ning, vice president of Peking University Third Hospital and director of the Center for Infectious Diseases: If you have fever and related respiratory symptoms and need to see a doctor, you should go to the fever clinic. When visiting a doctor, observe the relevant regulations of the hospital, especially self-protection, wear N95 mask regularly throughout the whole process, and comply with the relevant requirements of the hospital for nucleic acid and antigen. If you suspect that you have related upper respiratory symptoms and are worried about the risk of going to the hospital, you can choose online medical treatment, find experts in infectious diseases, respiratory medicine, Chinese medicine and related departments for consultation, and judge whether you need to go offline for medical treatment.

6. The emergency department and fever clinic can prescribe medicine for up to three days, but it hasn’t recovered after three days. Do you need to go to the hospital for reexamination?

Shen Ning: The self-limiting process of upper respiratory tract infection is about 5-7 days. Many patients’ symptoms are not completely relieved after 3 days. If the symptoms are relieved to a certain extent after 3 days of medication, there is no need to rush to return to the clinic. It is recommended to further observe the changes of symptoms. If the symptoms get worse, you must go to the hospital for a follow-up visit.

7. Can Chinese medicine and western medicine be taken together to treat Covid-19 infection? Can a variety of Chinese patent medicines be eaten together?

Liu Qingquan, President of Beijing Hospital of Traditional Chinese Medicine: At present, according to the research and clinical observation, Chinese patent medicines for treating COVID-19 and colds can be combined with western medicines such as antipyretic and analgesic drugs. Just to be on the safe side, Chinese medicine and western medicine should be separated by half an hour. If the ingredients of "Chinese patent medicine" used include drugs with western medicine for relieving fever and pain, attention should be paid to the combination of them, and side effects may occur after the drugs are superimposed. It is recommended not to combine several drugs, including traditional Chinese medicine and western medicine. As a result of combined use, there will be overlapping of drug doses, which has certain risks and will not improve the curative effect.

8. What traditional Chinese medicines can be selected?

Liu Qingquan: At present, all the Chinese patent medicines for treating colds and flu, especially those with wind-heat syndrome and external cold and internal heat (cold containing fire), have a very good effect on treating Omicron mutant.

9. How to protect pregnant women?

Qiao Jie, Dean of Peking University Third Hospital and Academician of China Academy of Engineering: If pregnant women’s family members are infected, they should be relatively isolated in space as far as possible if possible, and their living items should be separated as much as possible, and the bathroom should be disinfected, and the living space should be ventilated as much as possible. If a colleague is positive, try to work at home as much as possible. If you must work in the same space at the same time, pay special attention to the ventilation of the office space and wear N95 mask. Pregnant women should go to public places as little as possible, and do not get together or have dinner. Pay attention to hand hygiene while wearing a mask. Maintain balanced nutrition, adequate sleep and a positive and optimistic attitude. Pay attention to the standardized wearing of N95 mask when you go to the hospital for check-up, and reduce the waiting time. If you have any questions, you can consult in the form of online medical care.

10. What are the symptoms of pregnant women infected with Covid-19? Will it affect the fetus?

Qiao Jie: After the pregnant women were infected with Covid-19, the overall incidence, symptoms and course of disease were similar to those of the general population. The main symptoms were upper respiratory tract infection, such as cough, sore throat, sneezing, stuffy nose, runny nose, general aches and fever, and the severity was very few. The course of disease is basically 5-7 days, and the severe cases are mainly related to basic diseases, such as poor liver and kidney function, hypertension, diabetes, etc., which need to be treated in time. The mother has the protective barrier of placenta, so it is hardly transmitted to the fetus. However, if it is postpartum, it is best for Bao Ma to be isolated from the newborn or wear N95 mask to breastfeed.

11. How do pregnant women respond to symptoms?

Qiao Jie: When pregnant women have respiratory symptoms such as fever and dry cough, they can do nucleic acid test or antigen test to determine whether they are infected with Covid-19. Drink plenty of water, cool down physically, and choose traditional Chinese medicine available to pregnant women for symptomatic treatment. If western medicine is used to reduce fever, acetaminophen can be used for treatment if the temperature exceeds 38.5 degrees. When choosing antipyretic drugs, choose a single drug, and don’t stack it to reduce possible liver and kidney damage. Pay attention to monitoring heart rate, blood pressure and body temperature. Pregnant women in the third trimester should also pay attention to the monitoring of fetal movement, which can be monitored for one hour every day and have more than three fetal movements every hour. If the symptoms persist for more than 3 days, the fever does not improve after taking antipyretics, or fetal movement disappears, chest pain, chest tightness, abdominal pain, etc., you should contact the midwifery institution in time and see a doctor in time.

12. If COVID-19 is positive, can she give birth by herself?

Zhao Yangyu, director of the Department of Obstetrics and Gynecology, Peking University Third Hospital: Whether Covid-19 is infected or not, the choice of delivery mode is determined according to obstetric indications, and the doctor makes a comprehensive evaluation. For example, simple Covid-19 positive, no natural childbirth taboo (such as poor heart function, severe lung function, etc.), as long as you can tolerate the whole process of vaginal delivery, you can still choose natural childbirth.

13. What are the manifestations of children infected with COVID-19?

Qian Suyun, chief physician of Beijing Children’s Hospital: Most children mainly have fever, cough, runny nose and stuffy nose. Some of them are atypical symptoms, including fatigue, poor appetite, vomiting and even diarrhea. There are also some children who will have wheezing and hoarseness. However, the degree of children’s fever varies greatly from individual to individual, and some children can have a higher fever, even more than 39 degrees or 40 degrees. It is observed that most children have a fever in about 2-3 days. So the course of disease is about 3-5 days. The probability of serious illness is very low.

14. What medicines can families with children store?

Qian Suyun: Families with children should properly store some emergency drugs commonly used by children, but it is not recommended to store a lot of drugs. Improper storage may lead to children taking them by mistake. It is recommended to reserve drugs. The first category is antipyretic drugs. For children over 6 months, you can choose ibuprofen or acetaminophen, and one of them can be enough. Children between 2 months and 6 months are not suitable for ibuprofen, but acetaminophen can be used. For children within two months, it is not recommended to use antipyretic drugs routinely, and measures such as physical cooling can be taken and timely medical treatment can be taken. Cough is conducive to the discharge of respiratory secretions. Routine use of drugs is not recommended for children with mild cough. If there is nasal congestion and obvious cough, you can do atomization and wash your nose. At home, you can use a humidifier to increase the humidity in the air. If you have obvious cough, you can prepare some Chinese patent medicines for clearing heat and eliminating phlegm, and choose drugs suitable for your age, but don’t take two or more at the same time. Antipyretic drugs do not advocate taking the two drugs at the same time, and there is no need to take them alternately. Use drugs according to the age, dosage or doctor’s advice recommended in the instructions, and pay attention to the interval between two drugs. It is best for parents not to give drugs to their children according to their own experience or speculation. They can get medical advice and recommendations from professionals through the Internet.

15. Under what circumstances does the child need to be sent to a doctor?

Qian Suyun: The simplest way to distinguish is to look at the child’s mental state. If the child has fever and other symptoms, but he is in good spirits and can eat, drink and play after the fever has gone down, he can continue to observe and treat the symptoms at home. It is recommended to go to the hospital in the following situations: the fever lasts for more than 3 days and there is no sign of improvement; The child’s mental state is not good, including that the baby sometimes cries, is annoyed and is not easy to appease, and the older child is sleepy, listless and looks bad; In addition, cough is getting worse, which affects daily life and sleep; Some children wheeze, breathe faster, even have difficulty breathing, and have obvious hoarseness. Be careful of laryngitis and laryngotracheitis; If you have consciousness disorder or convulsion, you should see a doctor immediately. Children under three months are a special group, including newborns and infants. Once they have fever, it is recommended to see a doctor in time.

16. How should the elderly protect themselves?

Li Yanming, Director of Department of Respiratory and Critical Care Medicine, Peking Hospital: First of all, we should vaccinate, including whole-course vaccine and booster vaccine, which can obviously reduce the incidence of severe illness. Second, reduce going out, especially avoid going to closed places where people gather. If you really need to go out, wear a mask. Try to minimize contact with the external environment during the whole process, and wash your hands when you come back. Third, pay attention to keep warm while strengthening ventilation. You can put your elderly friends in another room and let them return to the room after the ventilation is over and the room temperature returns to normal. Fourth, to control basic diseases, we can buy medicines through various channels, or let relatives and friends buy medicines. Fifth, ensure regular sleep and nutrition, but don’t overeat. Reduce alcohol and tobacco as much as possible. Family members who don’t live with the elderly can reduce their visits and reduce the chances of virus exposure in the near future. If the co-residents are infected with Covid-19, they can live alone if conditions permit. If conditions do not allow, it is necessary to have an independent room, close the door and strengthen ventilation. Patients should be cleaned and disinfected after touching toilets, door handles and faucets.

17. What are the precautions for drug use in the elderly?

Li Yanming: After the elderly are infected with Covid-19, we should first strengthen observation and monitoring. Second, we should strengthen daily care, including light diet. After infection, the gastrointestinal function of the elderly is not good. It is recommended to eat less and eat more meals to avoid vomiting after eating a lot of food at one time. Ensure sleep; Replenish a proper amount of water, combined with body temperature and sweating, a small amount for many times, to prevent gastrointestinal discomfort and increase heart load caused by a large amount of water supplement at one time. Third, the higher the body temperature and the older you are, the more careful you should use drugs to prevent the elderly from sweating a lot after using a fever to cause collapse or even hypotension; In addition, the fever should be slowed down, and the fever can be reduced by physical means; Avoid using multiple drugs together when using antipyretics and cold medicines. Fourth, the application of proprietary Chinese medicines should be less and more precise, and multiple proprietary Chinese medicines with the same function should not be used at the same time. Fifth, the elderly with basic diseases should strengthen the management of basic diseases. A large amount of water loss caused by fever may lead to a decrease in blood pressure. During the fever, especially when antipyretics are used, pay attention to blood pressure monitoring. If the blood pressure is lower than the normal level, the antihypertensive drugs should be reduced or even stopped, and then used as usual when the blood pressure returns to normal. The elderly may eat little after infection, so it is necessary to monitor the changes of blood sugar to prevent hypoglycemia. When the elderly have fever and weakness, they must prevent falling.

18. Under what circumstances do you need to send the elderly to the hospital?

Li Yanming: We should strengthen the observation of the elderly and understand their basic situation. Such as basal heart rate, basal blood pressure, respiratory rate per minute and body temperature. For the elderly with cardiopulmonary diseases, it is necessary to know their basic peripheral oxygen saturation. Observe the changes of the general situation of the elderly, such as conscious state, mental state, defecation and eating. If the following situations occur, you need to consider seeking medical treatment: First, symptoms such as fever persist or tend to worsen. Second, there are new symptoms, such as chest pain, dyspnea, incontinence or sudden immobility of limbs, especially unilateral immobility of limbs, or inability of the elderly to eat, nausea and vomiting, or drowsiness, unconsciousness and disorientation. In addition, the aggravation of basic diseases, such as coronary heart disease in the elderly themselves, leads to angina pectoris; It turned out that there was chronic obstructive pulmonary disease or asthma, and there was an aggravation of chronic obstructive pulmonary disease and asthma, and they all needed to see a doctor.

19. What should cardiovascular patients pay attention to?

Zhou Yujie, Executive Vice President of Beijing anzhen hospital: Patients with original cardiovascular diseases are taking basic drugs. Drinking more water after high fever may affect the symptoms of heart failure, such as drugs for relieving muscle soreness and cardiovascular drugs. At present, no adverse effects between them have been found, so there is no need to be anxious. Manage the basic diseases of the heart well, use the original drugs for cardiovascular diseases well, increase the body’s immunity, improve their sleep quality and overcome anxiety. Don’t stop taking drugs for cardiovascular disease prevention and control for a long time. If you have persistent chest pain, seek medical advice promptly. Pay attention to keep warm, control the intake of sugar, oil and salt, and keep moderate exercise, not too intense. Monitor blood pressure, heart rate and blood lipid regularly.

20. How to sterilize at home?

Lu Lian, Director of the Hospital Sense Management Office of beijing ditan hospital, said: The risk of being infected by household items after "Yangguo" home rehabilitation is very small. The family can do daily cleaning without terminal disinfection. You can unplug the refrigerator and wipe it with a wet towel containing alcohol. Food that is not sealed in the refrigerator is heated before eating. Wipe hard surfaces such as toilets, desktops and cabinets with alcohol wipes or chlorine-containing disinfectant. Cotton items can be washed normally in the washing machine, and the quilt can be dried in the sun. Physical disinfection methods such as sun exposure and heat are preferred at home. To do a good job of ventilation, it is recommended to ventilate 2-3 times a day for at least 30 minutes each time. Household disinfection should focus on cleaning, supplemented by chemical disinfection.

21. What should I pay attention to when disinfecting?

Peking Union Medical College Hospital: Spraying 75% alcohol in a confined space for air disinfection may easily lead to fire or even explosion. Use chlorine-containing disinfectant to disinfect the surface of metal countertops or leather products that are easy to corrode. Disinfectants cannot be used to directly disinfect the human body. Stimulating the airway after inhalation will lead to cough and even destroy epithelial cells. It needs to be wiped after spraying with disinfectant, and pure chemical action can’t completely disinfect it. After disinfection with chlorine-containing disinfectant, the list of objects should be cleaned. The concentration of disinfectant used should not be too high or too low. Different types of disinfectants should not be mixed. Disinfectant can’t be added to the laundry detergent, and a large amount of water is diluted during washing, which can’t play a disinfection role; Chlorine disinfection will corrode and destroy the inner container of washing machine.

22. How long can I return to work after the fever has gone down?

Li Dongzeng, Chief Physician, Department of Infectious Diseases, Beijing You ‘an Hospital: Under normal circumstances, the symptoms of cough, nasal congestion, runny nose and sore throat will be obviously relieved in 3 days after the body temperature is normal. When somatosensory sore throat and cough no longer affect sleep, it means that the body has basically recovered and is suitable for returning to work. After 7 days of onset in young adults, the nucleic acid gradually turned negative, and the infectivity was low. COVID-19 should still do a good job of respiratory protection after recovery, and do not lower the prevention and control standards. After returning to work, stick to wearing masks in crowded and closed public places, pay attention to hand hygiene, cough, sneezing and other etiquette. Don’t eat face to face in the canteen.

23. Is there a high chance of reinfection after rehabilitation?

Zhong Nanshan, academician of China Academy of Engineering: After being infected with Omicron once, antibodies will be produced in the body, which is equivalent to being vaccinated once. At present, the data show that after being infected with Omicron once, the rate of reinfection within one year is very small.

Wan Mobin, Chief Physician, Department of Infectious Diseases, Shanghai Changhai Hospital:There are three types of people who are more susceptible to repeated infections, including the elderly, people with basic diseases and people with poor immunity.Self-protection awareness should be strengthened after the cured confirmed patients in COVID-19 are discharged from hospital and asymptomatic infected people are released from isolation. Vaccination, wearing a mask, keeping a social distance of 1 meter, and trying to avoid being in crowded and poorly ventilated indoor spaces are still effective ways to prevent repeated infections. In addition, in daily life, we should also increase nutrition, especially increase the intake of protein, keep exercising, ensure a good attitude and improve the body’s immunity.The risk of reinfection, as well as the symptoms after infection, depends on many complicated factors, including the variation of variants, vaccination and previous physical conditions. It is true that a small number of infected people are at higher risk after reinfection, but for most people, there is no need to worry too much about the aggravation of symptoms after reinfection.

24. What are the taboos for vaccination?

Beijing Center for Disease Control and Prevention: The medical staff at the inoculation point are responsible for the taboo judgment, and the clinicians at the secondary and above medical institutions are responsible for the disease diagnosis. The diagnosis certificate issued should specify the recent detailed state of the patient, so as to facilitate the taboo judgment at the inoculation point. Taboos include: ① severe allergic reactions, such as anaphylactic shock and laryngeal edema, occurred during previous vaccination; ② Acute infectious diseases are in the fever stage and vaccination is suspended; ③ Vaccination is suspended for serious chronic diseases during acute attack, such as cancer patients undergoing chemotherapy, patients with hypertensive crisis, patients with coronary heart disease who have myocardial infarction, autoimmune nervous system diseases in the advanced stage, and epilepsy patients in the attack stage; ④ Life has entered the terminal stage due to serious chronic diseases.

25. Does it mean that the COVID-19 vaccine has not been vaccinated because of the basic disease and other reasons?

Wang Huaqing, chief expert of immunization program of China CDC: There was a serious allergic reaction after vaccination, so we can’t vaccinate this vaccine in the future. Most other situations belong to the situation of slow seeding. In the early stage, because of the basic diseases, the vaccine could not be vaccinated in the evaluation process, and most of them belonged to slow seeding. They have entered the stable period of the disease or the special treatment condition is over. After re-evaluating the conditions, it is still recommended to vaccinate as soon as possible.

26. Is the adverse reaction rate of COVID-19 vaccine for the elderly high?

Wang Huaqing: According to the current monitoring situation, the overall reported incidence of adverse reactions among the elderly aged 60 and above after being vaccinated with Covid-19 vaccine is slightly lower than that of people under 60, and the incidence of serious adverse reactions is basically similar to that of other people, which is less than one in a million.

27. How long is the interval between strengthening immunization?

Beijing Center for Disease Control and Prevention: Vaccination with COVID-19 vaccine can effectively reduce the risk of severe illness and death after infection. The elderly who have no vaccination contraindications and meet the vaccination conditions should be vaccinated as soon as possible, and the booster immunization should be completed as soon as possible after 3 months of complete vaccination.

28. Who is the target group of the second dose of booster immunization?

According to the "Implementation Plan for the Second Dose of Enhanced Immunization of Covid-19 Vaccine" (hereinafter referred to as "Implementation Plan") issued by the Comprehensive Group of Joint Prevention and Control Mechanism for novel coronavirus Epidemic in the State Council, at this stage, on the basis of the first dose of enhanced immunization, the second dose of enhanced immunization can be carried out among people with high risk of infection, people over 60 years old, people with serious basic diseases and people with low immunity.

29. How long is the interval between the second dose of booster immunization?

According to the real world research and clinical trial data at home and abroad, combined with the actual vaccination in China, the time interval between the second dose of booster immunization and the first dose of booster immunization is more than 6 months.

30. What vaccines can be selected for the second dose of booster immunization?

According to the progress of vaccine research and development, all vaccines approved for conditional marketing or emergency use can be used for the second dose of booster immunization. Priority is given to sequential booster immunization, or the second dose of booster immunization with vaccines containing Omicron strain or with good cross-immunity to Omicron strain. The relevant combinations are as follows:

3 doses of inactivated vaccine +1 dose of Kangxinuo intramuscular recombinant Covid-19 vaccine (adenovirus type 5 vector); 3 doses of inactivated vaccine +1 dose of recombinant Covid-19 vaccine (CHO cells) of Chifeilongkema; 3 doses of inactivated vaccine +1 dose of recombinant Covid-19 vaccine (adenovirus type 5 vector) for Kangxinuo inhalation; 3 doses of inactivated vaccine +1 dose of Zhuhai Livzon recombinant Covid-19 fusion protein (CHO cell) vaccine; 2 doses of Kangxinuo intramuscular adenovirus vector vaccine +1 dose of Kangxinuo inhalation recombinant Covid-19 vaccine (adenovirus vector type 5); 3 doses of inactivated vaccine +1 dose of Chengdu WEEK recombinant Covid-19 vaccine (sf9 cells); 3 doses of inactivated vaccine +1 dose of Beijing Wan Tai nasal spray influenza virus carrier Covid-19 vaccine; 3 doses of inactivated vaccine +1 dose of Zhejiang clover recombinant Covid-19 protein subunit vaccine (CHO cells); 3 doses of inactivated vaccine +1 dose of recombinant Covid-19 bivalent S trimer protein vaccine from Shenzhou cells.
