随着放电等离子体在各个领域应用的不断扩大，两相体放电问题越来越重要，需要解决的基础问题之一即是两相体中放电发生、发展的特点和规律及影响因素。采用21种不同的介质材料研究直流电压下两相体放电的效应，由实验结果可知介质的介电常数对放电路径基本无影响，而介质颗粒的粒径大小对两相体放电路径的选择起决定作用，即粒径效应。此外，对颗粒介电常数、电场畸变、光电离作用和颗粒荷电等几个方面进行研究，可知两相体放电的粒径效应与颗粒粒径大小紧密相关。

With the continuously expanded application of discharge plasmas, the two-phase mixture discharges （TPMDs） are more and more important. The initiation and propagation of discharge, in terms of characteristics and influence factors are considered as the fundamental problems to be studied. 21 kinds of different dielectric materials were used to investigate the effects on TPMDs. Experimental results indicated that the dielectric constant has little influence on the discharge path while the macroparticle sizes play a decisive role, which are called the effects of macroparticle sizes. From the study of the macroparticle dielectric constant, the distorted electrostatic field, the photoionization and the saturation charge, it can be seen that the effects of TPMDs are highly correlated with the macroparticle sizes.
