| 摘 要： | 用美国GOW—MAC公司的气相色谱仪和Agilent公司的气相色谱仪对某卫星气体贮箱在氦气置换化验过程中发现的未知杂质进行试验分析，经分析未知杂质的来源可能是所用气体贮箱处理时的残留物。试验发现，氧化剂贮箱氦气和燃烧剂贮箱氦气经3次氦气置换后未知杂质的色谱峰消失。提出了消除未知杂质的的建议。

| Abstract: | The excrescence during the helium replacement in satellite gas store case was tested and analyzed by using gas chromatography of GOW-MAC and Agilent company. The possible sources of the excrescence are the original gas and the residue from the store case disposal. The peak of excrescence disappeared after three replacement. Some proposal on how to eliminate the excrescence were given. |
