| 摘 要： | 采用火花放电的方法模拟研究了大气对流层中闪电过程消除SF6的可能性．以气相色谱、红外光谱为主要分析手段，研究了闪电过程中SF6的分解反应机理及对该反应的影响因素．结果表明，SF6在闪电过程中，被分解并生成多种含硫、氟、氧的化合物．大气压强、H2O等对SF6的放电反应有影响．基于实验结果，对SF6在闪电过程中的反应途径作了探讨，并估算了实际大气中由闪电所引起的SF6的分解量．

| Abstract: | The discharge reactions in SF_(6)-O_(2) system were studied for searching the dissociation of SF_(6) in the lighting. The main products of these reactions were determined by Gas Chromatography and FT-IR spectrum. The results showed that the system can dissociate SF_(6), but the pressure and H_(2)O will effect the reaction. Based on the results, the mechanism of the reaction in the system was discussed. The dissociation of SF_(6) in the lightning process under practical situation was estimated as well. |
