飞行体在近地空间中运行的电双层形成

The Double Layer Effect on Motion of Moving Body in Space

该文采用计算机模拟计算的方法来讨论空间飞行体前端电双层的形成和特性．对粒子分布函数和密度函数所满足的Ｖｌａｓｏｖ方程和Ｐｏｉｓｏｎ方程进行数值求解。

In this paper,the formation and special property of double layer around the front surface of moving body have been studied in detail.By the simulation method of computer and solving Vlasov and Poisson equations,some important conclusions can be obtained.
