摘要： 为了削弱航天器有机介质内带电水平从而提高航天器运行的可靠性,分析了空间介质接地方式与电导特性对材料带电水平的影响,认为可采用非线性电导改性的方法来削弱聚合物材料的带电程度,并对几种典型的航天器聚合物介质进行了改性试验研究,获得了预想的非线性电导特性,认为对介质进行非线性改性可能成为未来对介质材料进行全防护的有效手段之一。

Abstract: In order to decrease the level of deep charged in the spacecraft organic dielectric and improve the stability and life span of the spacecraft.The effects of grounding modes and conductance property on the space dielectric were analyzed.It shows that the non-linear conductance modification can decrease the level of deep charged.The modification to the commonly used spacecraft dielectric was tested,and the preconceived non-linear conductance property was gained.The non-linear conductance modification was considered to be one of the most effective protection methods in deep charged for the dielectric material.
