摘要：

利用静电场模型对线筒式介质阻挡放电电场强度进行了计算，并对电子平均动能进行了估算。通过对单双介质阻挡放电(DBD)的对比，发现在相同的放电条件下，双介质DBD产生的电场强度和电子平均动能比单介质DBD的要大。这就很好地解释了在相同的放电参数下，甲苯的降解效率在双介质DBD中要比单介质DBD中大。

Abstract:

The electric field strength and electron mean kinetic energy in co-axial dielectric barrier discharge (DBD) were estimated based on static electric filed model. Through the comparison of the single dielectric layer DBD with the double dielectric layer DBD, it was found the electric field strength and electron mean kinetic energy in double dielectric layer DBD are greater than that in the single dielectric layer DBD under the same electrode configuration and discharge conditions. The calculation results can successfully applied to explain the toluene degradation efficiency in double dielectric layer DBD is larger than that in the single dielectric layer DBD under the same discharge parameters.

Key words: DBD, Electron mean kinetic energy, Electric field strength, Non-thermal plasma
