| 摘 要： | 采用火花放电的方法研究大气对流层中雷电反应产生COS的可能，以气相色谱、红外光谱为主要分析手段，对SO2－CH4－O2体系的反应进行了研究。结果表明，该体系在火花放电条件下会生成COS。原料气的初始强、放电时间和外加气体对COS的生成量都有影响。生成的COS也会在放电条件下分解。基于此，对该放电反应的机理作了探讨，并估算了清洁及污染大气中可能生成的COS的浓度。

| Abstract: | The discharge reactions in SO 2 CH 4 O 2 system were studied for searching the formation of COS in the lightning. The main products of these reactions were determined by Gas Chromatography and FT\|IR spectra. The results showed that the system can produce COS, but the pressure of SO\-2 and CH\-4,discharge time and other added gas effect the amount of COS produced. At the same time, the COS dissociated partly under the same condition. The mechanism of the reactions in the system was discussed. |
