摘要： 航天器表面在轨道运行中会出现电荷积累现象,尤其高轨道航天器这种现象更为严重。改善航天器表面的导电能力是解决这一问题的有效途径之一。据此,本文对两种常用的航天器表面涂层在模拟空间亚暴环境下电导性能的变化及其规律作了实验研究。

Abstract: The phenomenon of Space Charge Accumulation (SGA)of spacecraft will exhibit if it operates at its orbit-especially at high altitude orbit. Improving the conductivity of spacecraft surface is one of the most useful ways to solve the problem. The surface conductivity changes and the regularities of two common thermal control paints have been studied in simulated substorm condition. Several significant results have been obtained.
