摘要: 卫星表面在地磁亚暴环境下积累电荷的现象是必然的。由于表面间物性的差别,这种积累将是不均衡的,然而一旦建立了电势差,那末表面与表面,表面与构架间就会存在电荷交换,使电势差逐渐趋于减小。文章试图通过物理模型的建立,由此推导出面间电势差变化与表面电势值及表面的电导、电容的关系,从而建立一种明确的数学模型,以利卫星表面充电状态的分析。

Abstract: The charge accumulation on satellite surface in substorm is not avoidable.Owing to the difference in physical characteristics between sur- face materials,the accumulation of charge will not be in equilibrium.How- ever,the potential difference no sooner establishes than the exchange of charge between surface and frame of satellite begins to decrease gradual- ly. The relationship among the change of potential difference,the surface potential value,the surface conductivity and the capacitance has been de- duced by means of establishing a physical model.Thus a mathematical model can be obtained.The analysis of charging state on a satellite surface can be realized by the mathematical model.
