从遥远海洋到重污染地区,在很宽的大气条件下,用灵敏度分析法研究了光化学典型产物Ｏ３的形成机理及其化学耦合作用,指出了影响形成Ｏ３的重要反应,在一些条件下,Ｏ３浓度对一些重要化学反应的速率常数的归一化灵敏度系数异号,由于碳、氮化合物的化学耦合作用的非线性现象使Ｏ３生成增加．大气中一些重要的光化学产物如Ｏ３,ＨＮＯ３,ＨＣＨＯ,Ｈ３Ｏ３等形成中,ＤＭＳ的化学耦合是弱耦合．
From the remote ocean to heavily polluted areas, the formation mechanism and chemical coupling of the typical photochemical product O3 are studied by sensitivity analysis under a wide range of atmospheric conditions. The important reactions that affect the formation of O3 are pointed out. Under some conditions, O3 The normalized sensitivity coefficients of the rate constants for some important chemical reactions vary signi fi cantly due to the non-linear phenomenon of the chemical coupling of carbon and nitrogen compounds that leads to increased O3 generation. Some important photochemical products in the atmosphere such as O3, HNO3, HCHO, H3O3 and other formation, DMS chemical coupling is weakly coupled.
