中文摘要:
      目的 通过卫星热试验过程中采取烘烤出气措施后舱体内部污染状况分析， 为卫星试验过程中污染控制工作提供有效方法。方法 使用石英晶体微量天平（QCM）及真空度测试系统， 对星内污染沉积量与真空度进行实时监测， 比较卫星高温静置工况前后沉积量与真空度测试量值的变化。结果 整个热试验过程中星内污染出气沉积量为1.8×10-5 g/cm2， 高温静置工况星内污染出气沉积量为5.67×10-6 g/cm2， 高温静置工况开始前星内真空度为2.9×10-2 Pa， 第一次高温循环工况开始时星内真空度为2.3×10-3 Pa。结论 整个高温静置工况星内污染出气沉积量约占整个热试验过程中的30%， 且使得星内真空度由10-2 Pa的量级降低到10-3 Pa的量级， 因此高温静置烘烤措施能够有效去除卫星材料出气污染。
英文摘要:
      Objective To study the contamination condition in satellite cabin after baking operation in the process of thermal test, so as to provide an effective method for contamination control of satellite. Methods The contamination deposition mass and the vacuum pressure were monitored with the quartz crystal microbalance (QCM) and the vacuum test system. The changes of the deposition mass and the vacuum pressure before and after quiescence in high temperature were compared. Results The contamination deposition mass was 1.8×10-5 g/cm2 in the process of thermal test and the contamination deposition mass was 5.67×10-6 g/cm2 in the process of baking phase. The vacuum pressure was 2.9×10-2 Pa before the bake-out phase and the vacuum pressure was 2.3×10-3 Pa before the first temperature cycle phase. Conclusion The contamination deposition mass in the process of baking phase was about thirty percent of that in the thermal test. The baking method can decrease the vacuum pressure level from 10-2 Pa to 10-3 Pa, which can decrease the contamination condition in satellite cabin effectively.
