【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.更多还原

【Abstract】 The discharge reactions in SF₆-O₂ system were studied for searching the dissociation of SF₆ 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 SF₆, but the pressure and H₂O will effect the reaction. Based on the results, the mechanism of the reaction in the system was discussed. The dissociation of SF₆ in the lightning process under practical situation was estimated as well.更多还原
