摘　　要：研究了平板-平板电极、多针-平板电极和筛网电极3种电极结构DBD的放电特性,通过测量电压-电流波形图及放电发光图比较了它们的区别,并从放电机理角度对实验结果作了解释。结果表明:平板-平板电极DBD表现为稳定的细丝状放电。而多针-平板电极DBD融合针尖的电晕效应,使得放电空间中呈现扩散圆锥形放电。筛网电极DBD可以实现大气压辉光放电(APGD),放电更加均匀,放电空间内看不到放电细丝的存在。The dielectric barrier discharge characteristics of three electrode configurations, plate-plate, multineedle-plate and mesh, are studied and compared and distinguished by means of measured voltage-current oscillograms and discharge photos. Based on discharge mechanism, the experiment resuits are analyzed. Results show that： the plate-plate DBD displays filamentary discharge mode and the the muhineedie-plate DBD displays diffuse conical mode and the mesh electrodes DBD expresses homogeneous discharge mode without filament, which can he used to obtain atmospheric pressure glow discharge .
