摘要
闪电是常见的对流层大气火花放电现象 .本文利用火花放电技术模拟研究了自然界闪电作用下COS的生成和转化反应 .结果表明 ,CS2 和SO2 CH4 体系在火花放电条件下都会生成COS ,前者是更重要的源 ;生成的COS也会继续转化为CO、CO2 、SO2 和SO3 等 ;O原子和OH自由基是COS生成和转化的关键因素 ;整个过程中COS的转化量多于生成量 .
Lightning is a common phenomenon of spark discharge of the air in the troposphere. Spark discharge method was used to take simulative investigations on the production and conversion reactions of COS under lightning here. The results showed that the system of CS 2 and air as well as that of SO 2 and CH 4 could produce COS under the condition of spark discharge.However,the former was more important.Meanwhile,COS could be converted into other substances,such as CO,CO-2,SO-2,SO-3 and so on by discharge.And t...
