| 摘 要： | 文章研究热缩套管的体电阻率和击穿电场强度在空间带电粒子辐照环境中的退化情况。分别利用γ射线和低能电子模拟低地球轨道带电粒子辐照环境，研究热缩套管辐照前后性能变化情况。试验结果表明，热缩套管的击穿电场强度在辐照后变化不明显，而体电阻率有不同程度的变化，电子辐照后热缩套管的体电阻率退化比γ射线辐照后的更为严重。

| Abstract: | The effects of the space radiations on the volume resistivity and the breakdown field strength of five kinds of heat-shrinkable sleeves are studied in this paper. The γ-ray and the low energy electron were used to simulate the space charged particle environment, respectively. It is shown that the breakdown field strength of the samples is little affected by γ-ray and electron radiations, whereas the volume resistivity of the heat-shrinkable sleeves is degraded to various degrees after different radiations. More severe degradation is caused by electron radiation than by γ-ray radiation. |
