为了研究大气压下氩气(Ar)中掺杂氨气(NH3)的Ar/NH3介质阻挡辉光放电的放电机理, 通过建立一个多粒子的自洽耦合流体模型, 采用有限元方法进行数值计算, 得到了气体间隙压降、介质表面电荷密度、放电电流密度随时间的周期变化波形, 以及带电粒子、中性粒子与空间电场强度的时空分布. 仿真计算结果表明: 气体间隙的周期击穿过程主要由气隙电压控制, 并受气隙两侧介质极板上积聚的表面电荷的影响. 气隙间带电粒子密度和电场强度的时空分布表明本文的放电过程存在阴极位降区、 负辉区、法拉第暗区、等离子体正柱区等辉光放电的典型区域, 放电模式为大气压辉光放电. 在Ar/NH3 等离子体中, 主要的正离子为NH3+, 其次为Ar2+, 主要的负离子为NH2-; NH3分解产生的主要的激发态分子为NH, NH2和N2H3, 而最终的稳态产物主要是N2和H2.
