【 摘 要 】

This paper focused on how to suppress filamentous discharge and achieve glow discharge in air. In this study, glow discharge plasma was generated under low pressure by the plate electrode using dielectric barrier. Pulse supply and sinusoidal supply were adopted in this study and their influence on glow discharge were analyzed. Discharge characteristics under different air gap between the electrodes were studied. In addition, we studied the influence of dielectric barrier conditions on the glow discharge. The results show, pulse discharge, shortening the discharge gap and suitable dielectric barrier conditions, can effectively prevent the occurrence of filamentous discharge which contributes to achieve the glow discharge in air.
