在弱电离等离子体中，固体粒子是负电荷和正电荷的主要载体，流体加速度在建立电荷分离产生的电场方面可以发挥类似于重力的作用。本文指出，在没有重力的情况下，流体运动的性质、电离结构以及产生足以引起放电的电场所必需的颗粒大小和电荷分布可以从线性声波中的电场计算中推断出来
Fluid acceleration can play a role similar to that of gravity in the establishment of charge separation generated electric fields in weakly ionized plasma in which solid particles are the dominant carriers of both negative and positive charge. It is pointed out that the properties of fluid motions, the ionization structures, and grain size and charge distributions necessary to produce electric fields strong enough to induce discharge in the absence of gravity can be inferred from calculations of the electric fields in linear acoustic waves
