  • 摘要: 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二甲硫(DMS)和SO2的氧化机理及其化学耦合作用,DMS最重要的氧化机理是OH自由基的摘氢反应,对SO2是SO2与OH自由基的反应。在DMS和SO2的氧化过程中,碳、氮、氧化合物的化学耦合作用起着根本性的作用,重要的化学耦合反应是OH自由基的生成反应、消耗反应和NOx等的光化学引发反应等.
    Abstract: The mechanism of oxidation of DMS and SO2 and its chemical coupling has been studied with sensitivity analysis under a broad range of atmospheric conditions from remote ocean to heavily pol-luted area. The most important pathway for oxidation of DMS and SO2 is the subtraction reaction of DMS with OH and oxidation SO2 with OH. But the Chemical coupling plays and essential role in the oxidation. The important chemical coupling reactions are the production and destruction reactions of OH and the NOx photo-initiation reactions.
