摘　　要：基于低地球轨道空间等离子体对航天器的充电机理,根据电子、离子运动性质分析了飞船绝对电位与表面导电材料分布间的关系,讨论了对接放电过程中航天器与空间等离子体的交互作用,给出了其计算方法和相关试验结果。从空间环境角度为工程实现提供了理论依据和参考。The relationship between the absolute potential and the conduct material on the surface of the spacecraft was discussed according to the characteristics of the electrons and ions based on the charging mechanism of the space plasma to the spacecraft in low earth orbit in this paper. The interaction of the spacecraft and space plasma in spacecraft charging and docking discharging was analyzed. The calculation method and the experiment results were given out, which would provide a reference from the space environment for engineering.
