Is this swollen recently? The weather (smog) is so bad, how can we change this situation? What can we do?

Fog is an aerosol system composed of a large number of tiny water droplets or ice crystals suspended in the air near the ground, and it is the product of condensation (or sublimation) of water vapor in the air near the ground. The existence of fog will reduce air transparency and worsen visibility. If the horizontal visibility of the target drops below 1000 meters, the weather phenomenon of water vapor condensation (or condensation) suspended in the air near the ground is called fog. The phenomenon that the horizontal visibility of the target is 1000- 10000 meters is called light fog or mist. When fog is formed, the atmospheric humidity should be saturated (if there are a large number of condensation nuclei, the relative humidity may not reach 100%, and saturation may occur).

With the deterioration of air quality, cloudy days are increasing and the harm is increasing. Recently, many areas in China have incorporated the smog weather phenomenon into the fog as an early warning and forecast of disastrous weather. Collectively referred to as "haze weather".

Sulfur dioxide, nitrogen oxides and inhalable particles are the main components of smog. The first two are gaseous pollutants, and the last particulate matter is the chief culprit that aggravates smog weather pollution. They combine with fog and instantly turn the sky gray. The abbreviation of particulate matter is PM. At present, what Beijing is monitoring is PM 10, that is, pollutant particles with a diameter less than 10 micron. This particle itself is not only a pollutant, but also a carrier of toxic substances such as heavy metals and polycyclic aromatic hydrocarbons.

Sources of toxic particulate matter in cities: firstly, automobile exhaust. Large vehicles that use diesel are "recidivists" who emit PM 10, including buses, shuttle buses of various units and large-scale traffic? Truck, wait. Small cars that use gasoline emit gaseous pollutants, such as nitrogen oxides, which are easily converted into secondary particulate pollutants in foggy days, aggravating smog. Secondly, the waste gas produced by burning coal for heating in winter in the north. The third is the waste gas emitted by industrial production. For example, industrial kilns and boilers in metallurgy and electromechanical manufacturing industries, as well as a large amount of waste gas generated by the combustion of automobile repair and painting and building materials production kilns. The fourth is the dust generated by construction sites and road traffic.

At present, it is a very arduous task to obviously improve the current weather conditions, which requires the joint efforts of all of us. As a leader in the solar energy industry, Huang Ming has achieved:

In the noisy life of the world, you can feel this kind of out-of-touch comfort when you get home. Why not sweep away the fatigue of a day's work and feel the beauty of life?
