The superimposing surface and silent discharge reactor consist of double coaxial cylinders configuration. The reactor has three electrodes. The experimental results shown as follows.(1) NOx decomposition rate increase by at large air gap, by at low gas flow rate and by at large discharge current condition.(2) Discharge superimposing effect are depend on shortening of discharge rest time and spreading of discharge space.(3) NOx decomposition rate rather increase by 3 phase electric source system than by single phase electric source system.(4) NOx decomposition rate rather increase by high frequency electric source than by commercial electric source.(5) NOx decomposition rate increase by Superimposing sound wave on discharge space.These research results encouraged to design high power NOx decomposition plasma reactor.

叠加表面无声放电反应器由同轴双圆柱体结构组成。反应器有三个电极。实验结果如下。(1)在大气隙、小气体流量和大放电电流条件下，NOx分解率分别提高了1.5%、1.5%和1.5%。(2)放电叠加效应取决于放电静止时间的缩短和放电空间的扩展。(3)三相电源系统比单相电源系统有更大的NOx分解率。(4)与商用电源相比，高频电源能提高NOx的分解率。(5)在放电空间中叠加声波可以提高NOx的分解率，为设计高功率等离子体反应器提供了理论依据。
