摘要
该文采用双流体模型，在高频场对密度扰动的调制作用基础上，又考虑了等离子体中带电粒子流的非残性效应，在等离子体中得到了一个包含这两种作用的电双层解．从而较合理地解释了实验室中产生电双层现象所必须引入的条件──必须有带电粒子流的注入．
In this paper,on the basis of two magneto-fluid model for two timescale,considering the modulational action of high frequency field on low frequency perturbation and the nonlinear effect of the charged particles fluid in plasma,a result which is composed of the two actions has been obtained. This result can reasonably explains that we need a charged particles fluid or a potential drop in plasma,if we produce a double layer in laboratory.
