总装材料对氦气吸附性能的试验研究

Experiments on helium adsorption capability of materials used in satellite assembly

摘要: 文章对卫星总装中所使用的部分吸附性材料进行了氦气吸附性能试验研究。通过试验及分析证明了所采用的吸附性材料对氦气的吸附很小，在采用累积法进行卫星检漏时，吸附性材料对检漏结果的影响可以忽略。

Abstract: Experiments were conducted to investigate the helium adsorption capability of absorptive materials used in satellite assembly. It is concluded that the helium adsorption capability of absorptive materials is small, and the effect on the leakage test result when using the accumulating method is negligible.
