摘　　要：通过电压-电流波形图和电压-电荷李萨育图形的测量,研究了空气中多针-平板电极介质阻挡放电特性,比较了这种放电和平板-平板电极介质阻挡放电的区别。通过实验研究了放电间隙距离、多针电极针的密度、阻挡介质材料性质对多针-平板电极介质阻挡放电放电功率的影响。实验结果表明,在相同的条件下,与平板-平板电极介质阻挡放电相比,多针-平板电极介质阻挡放电消耗较大的放电功率;放电空间消耗的功率随外加电压和介电常数的增加而增加,随气隙距离的增加而减小。The discharge characteristics of multineedle-to-plane dielectric barrier discharge(DBD)are shown by measurements of their voltage and current waveform,and Lissajous figure,and the differences between this discharge and plane-to-plane DBD are compared.The influˉences of the applied voltage,the gas gap distance,and the dielectric permittivity of the barrier on the power dissipated in DBD regime are studied experimentally.Results show that,under the same conditions,more power is dissipated by multineedle-to-plane DBD compared with plane-to-plane DBD.The dissipated power increases with the increasing of applied voltage and diˉelectric permittivity of the barrier,and decreases with the increasing of gas gap distance.
