摘　　要：对低温等离子体净化汽车尾气的化学动力学进行了研究。根据波尔兹曼分布规律,推导出了高温电子撞击气体分子的反应速率常数公式;用数值模拟方法分析了NO的反应过程,通过模拟和实验验证,得出了O2浓度和输入电压对NO去除的影响。A chemical kinetics study on the automobile exhaust control using non-thermal plasma is carried out in this paper. On the basis of boltzmann distributing, the formula of reaction rate constant for the impacting of high-temperature electron upon gas molecule is derived out. The reaction process of NO is analyzed by the numerical simulation method. Through imitation and experiment, the effects of the 02 concentration and the input voltage on the removing rate of NO are drawn from.
