| 摘 要： | 卫星上所用非金属材料，在空间真空环境下存在出气行为，产生污染效应。为了研究这种出气行为，本文以扩散理论为理论依据，推导材料出气模型。利用空间分子污染气体分析仪，测试了星用非金属材料的出气速率变化，对所测数据进行曲线拟合，通过试验和理论分析，证实了模型推导的正确性，结果表明：经过6h的真空加热预处理能够有效减少出气污染。

| Abstract: | In space environment, the nonmetal materials will outgas, This action will result in contamination effect. Therefore, it is essential to study outgassing by means of micromechanics. Diffuse theory is used to build the outgassing model. By using an analytical device, the outgassing rate is measured and analysed theoretically. Results show that outgassing contamination can be reduced effectively when the materials are heat treated previously in vacuum for 6 h. |
