摘要
综述了目前国内外对二甲基硫 (DMS)的海—气通量的研究状况 ,指出了DMS的海—气通量受很多因素的影响 ,运用不同的模型计算值相差很大。此外本文着重论述DMS进入大气后被OH和NO3 等自由基的氧化机理及其氧化产物对酸雨酸雾的贡献以及DMS、凝云结核 (CCN)、气候系统之间的关系。
Reviews on the current studies at home and abroad on the sea to air flux of DMS were made, pointing out that the flux of DMS is influenced by many factors. There is great difference between the results coming from the different models. Besides, this paper focuses on the oxidation mechanisms of DMS by OH and NO 3 radicals after it enters the atmosphere, the oxidation products contribution to acid rain and fog and the relationships within the DMS, CCN and climate system.
