| 摘 要： | 利用火花放电技术模拟研究了自然界闪电作用下CS2转化为COS的反应. 结果表明, 放电条件(电压3000 V)下CS2(初始分压为1.33×103 Pa)能与空气(25 ℃, 103 Pa)中的氧气、水蒸气作用, 转化为COS以及其他含硫含碳产物(CO、CO2、SO2等); CS2初始分压、水蒸气和放电时间等因素对COS生成量有明显的影响. 并在实验基础上结合多种理论, 探讨了相关过程的大气闪电反应机理. 这些结果可为自然界闪电条件下的硫循环、碳循环过程的研究提供重要依据.

| Abstract: | Spark discharge method was used to take simulative investigations on the conversion reaction from CS2 to COS by lightning. The results showed that 1.33 x 10(3) Pa CS2 could act with O2 or H2O in the atmosphere (25 degrees C, 10(5) Pa) under electric discharge conditions (V = 3000 V), and COS was produced as well as other species such as CO, CO2, SO2 and so on. Factors such as CS2 concentration, water vapor and discharge time played important roles in the formation of COS. Based on these results and several theories, possible mechanisms of correlative processes during thunderstorms were proposed here, which could contribute to give evidence for the conversion from CS2 to COS by lightning during thunderstorms. |
