摘要： SRB、G86涂层和铝阳极化着(黑)色是卫星表面热控用的材料。在轨道上,它们将直接与空间等离子体环境相接触,因此它们表面积累电荷的性质对是否会由它们引发放电、起弧、击穿等物理效应是至关重要的。为此在综合模拟空间环境下对它们的充电性能进行评价是十分必要的。通过实验评价可以正确了解它们的表面积累电荷的情况及其变化规律,为在工作中恰当的使用或改进提供科学依据。

Abstract: The Paints of SRB and G86,and black anodized A1 areused on satellite surface for thermal control.Because they are directlyin contact with the plasma environment in space.So the properties ofthe charges accumulated on their surface are very important to controlthe physical effects of arcing,discharging and breakthrough.So it willbe very important to evaluate the charging performance in the combinedsimulation space environment.In this article,the evaluation resultshave been given.The results indicate how to use and modify themcorrectly.
