In this study, the temporal variation of an electric potential distribution was measured in a surface dielectric barrier discharge experiment using the Pockels effect. A branching pattern and homogeneous distribution were respectively observed when positive and negative voltages were applied. When continuous alternating current was applied to the electrode, the spatial distributions of the electric potential significantly changed between the first and subsequent discharge cycles. The results indicate that the electrostatic repulsive forces caused by the residual charges on the dielectric surface affect the dynamic patterns of the discharge morphology.

表面介质阻挡放电电势的时空变化

在这项研究中，使用普克尔斯效应在表面介质阻挡放电实验中测量了电位分布的时间变化。当施加正电压和负电压时分别观察到分支模式和均匀分布。当向电极施加连续交流电时，电势的空间分布在第一次和随后的放电循环之间发生了显着变化。结果表明，由电介质表面残留电荷引起的静电排斥力影响放电形态的动态模式。
