New coronavirus aerosol spread? What is aerosol? This starts with flattering and depleted uranium bombs
What exactly is aerosol? "Aerosol" is a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gas medium, with a size of 0.001-100 μm. The virus is dispersed in aerosol and is inhaled to cause infection. In fact, aerosols are very common in life. For example, smoke, haze, hair spray, aerosol perfume, can be suspended in the air.
Everyone is responsible for fighting the epidemic
It has been determined that pneumonia caused by the new coronavirus can be spread through aerosols.
At the press conference of the Shanghai Leading Group for Epidemic Prevention and Control on February 8, 2020, Zeng Qun, deputy director of the Shanghai Municipal Civil Affairs Bureau, emphasized the importance of further strengthening the prevention and control of the epidemic within the family:
Health and anti-epidemic experts emphasized that the main routes of transmission of new coronary pneumonia that can be determined at present are direct transmission, aerosol transmission and contact transmission.
So, what exactly is aerosol? This starts with depleted uranium bombs and flattery!
"Aerosol" is a colloidal dispersion system formed by small solid or liquid particles dispersed and suspended in a gas medium, with a size of 0.001-100 μm. The virus is dispersed in aerosol and is inhaled to cause infection. In fact, aerosols are very common in life. For example, smoke, haze, hair spray, aerosol perfume, can be suspended in the air. You can still smell the perfume through the mask, because the aerosol formed by aerosol perfume is very small, suspended in the air, and can penetrate the gaps of the mask. However, don’t panic. The virus is spread by aerosols, and it is not easy to spread. It depends on the aerosol concentration, residence time, etc., so wearing a mask and washing hands frequently and avoiding physical contact is still the best preventive measure.
In the war, the powerful thermobaric bomb is the result of the explosion of high-energy combustion materials mixed into aerosols. Another example is the radioactive damage of depleted uranium armor-piercing projectiles. After the depleted uranium core of the armor-piercing projectile hits the target, the depleted uranium material burns and breaks to form an aerosol that is contaminated by the human body after inhalation. Because depleted uranium in a static state is very safe and has extremely low radioactivity, only when it is heated and burned and broken into aerosols, the radiation risk is relatively great after being inhaled by the human body.
When many people talk about depleted uranium bombs, they will talk about uranium discoloration. In fact, depleted uranium is also very common in our lives. For example, many large civil airliners have hundreds of kilograms of depleted uranium as counterweights on the rudders and ailerons. On October 4, 1992, near Amsterdam, the Netherlands, an Israeli Boeing 747 cargo plane crashed into a residential building, causing a fire. The air crash killed 43 people, including 4 crew members and 39 residents.
In the survivors of the disaster, a mysterious radiation disease appeared after several years. Experts first judged that the US military’s chemical weapons agents were loaded on the air crash cargo plane, a total of 190 kilograms of dimethyl methylphosphonate. This military chemical is usually a simulant used in chemical warfare exercises. However, after this chemical is burnt violently, it usually does not have a large long-term impact on the health of surrounding residents.
There must be other reasons. When the wreckage was cleaned up afterwards, it was discovered that 150 kilograms of depleted uranium had disappeared from the 400 kilograms of depleted uranium used for counterweights. This part of the depleted uranium formed radioactive aerosol oxides during the fire and dispersed to the surrounding areas, causing long-term radioactive pollution. Later, Boeing cancelled the use of depleted uranium as a counterweight and replaced it with other safer high-density metals.
Aerosols cause the virus to spread, and it has also broken out in Australia, this time it was caused by flattering. This place in Australia is actually full of strange amorous feelings. For example, big snakes can enter the toilet in the village through the sewer pipes. Spiders with big hands suddenly appear in the corners of the house, waiting for people's scalps to tingle. Flies are also very strange, in a sparsely populated place, there is no Internet celebrity cafeteria... Septic tanks, so that the flies that eat shit can't grab the shit, so they have evolved to chew nectar and chew sweet stick juice. After all, the European prisoners were sent to Ningguta in the South Pacific, and the living environment was not too sloppy, otherwise they would be cut by the plague and belch directly.
Clean and tidy is a forced choice for Australians for a hundred years, otherwise they will be destroyed by nature's razor. However, in 2007, Australians who love cleanliness were taught a lesson by nature. At that time, there was a relatively serious horse flu in Queensland. Even if the Australians carried out strict quarantine measures, there were still weird horse flu transmission incidents between horse farms. It was clear that some horse farms were separated by several miles. The clean racecourse that hadn't entered the city was still hit.
Later, after the scientists conducted a review study and ruled out insects and birds, they were shocked to find that it was probably due to the sound of the noses of many horses, and even the flattery that they released, forming a considerable smell of air masses, carrying them inside the body. The horse flu virus drifted in the wind to the nearby racecourse and finally caused the horse racing industry in Brisbane to plummet.
The above-mentioned taste air mass is the internal smell that people can smell as soon as they enter the pet store. This is also called aerosol in the physical definition. Just look at the name and you will know that this is a colloid , Which means that this flattering is not easy to settle. I want Haiyanhe to wait for half an hour.
The recent new coronavirus is also the same. As long as a source of infection stays in a room with a closed window, he shit on the toilet and the aerosol formed may be able to flee through the ventilation duct of the bathroom. Vents on other floors. The virus in the excrement can flow through the sewage pipe to form a stronger aerosol, and enter the bathroom of other residents through the dry floor drain. Once the residents' immunity is reduced, there is a possibility of being recruited. In 2003, more than 300 owners in the Amoy Gardens in Hong Kong were brought down by SARS. The cause was only a super communicator having diarrhea in the bathroom. In the end, the entire building was almost destroyed.
The virus aerosol sounds very scary. It's just like the poisonous miasma in Yunnan Worm Valley, which made Chen Yulou a blind man. It was terrible. Hu Bayi and Fatty Wang were smelling it, and they turned their heads and fled back to Pan. home. However, in fact, aerosols are far less fierce than toxic miasma. It takes a certain amount of confined space and time to form, such as elevators, rooms, convenience stores, etc., and some aerosols can be accumulated by infected persons breathing and sneezing. On the street, it’s almost impossible, because the infinite air will dilute the virus aerosol, and the concentration can no longer infect people, but it’s better not to get together and chat. In those few seconds, the infected person exhales The sol hasn't been diluted by air yet, so it's easy for others to get caught.
Therefore, the room must have windows open regularly for ventilation, the floor leaks must have water seals, and the bathroom vents must be treated as appropriate. Finally, don't go together and play mahjong. If you are going crazy at home, you have to hold back. Is it good to live? The clouds are clear and the mist is clear, and the breeze is smooth and there is no dust.
