雾霾形成的物理原理解析

Analysis of the Physical Principle of Fog and Haze Formation

摘要: 雾(灰)霾的形成是自然活动、科技、人类活动的结果。今年两会中科院院长白春礼在回答相关雾霾问题时指出，雾霾的三大“源”凶：燃烧、汽车尾气、扬尘，但是pm2.5的第二次爆发原因很复杂，包括一些化学反应。其实，雾霾形成的原因是：1) 雾霾颗粒的积累，即燃烧、汽车尾气、扬尘作用的结果；2) 雾霾颗粒向上的动力——热空气向上运动，无线传播，即向上运动的电磁波网；3) 无持续风向。三个条件都具备才会爆发持续的雾霾天气，缺一不可，pm2.5的二次爆发正是上述三个条件共同作用的结果。

Abstract: The fog and haze formation is the result of natural activity, science and technology, and human activity. This year President Bai Chunli of NPC and CPPCC CAS indicates the reasons of the fog and haze in answering related problem, which are combustion, vehicle exhaust, and dust. But the reasons of the second outbreak of pm2.5 are complex, including some chemical reaction. In fact, the reasons of the fog and haze are: 1) the accumulation of the fog and haze, namely the results of combustion, automobile exhaust, and dust effects; 2) the fog and haze particles’ upward momentum—hot-air upward movement and wireless communication, namely the electromagnetic wave net sports; 3) no sustained wind. These three conditions indispensable lead to persistent fog and haze weather, and the second outbreak of pm2.5 results from the above three conditions together.
