| 摘 要： | 载人航天器舱内使用的大量非金属材料在密封环境条件下会缓慢脱出有害气体。文章通过选取舱内典型的非金属材料，进行了材料在低压环境下脱出有害气体的试验，获得了低压环境对材料脱气速度和质量分数的影响，研究结果可为航天器舱内环境控制提供参考。

| Abstract: | Nonmetallic materials used in the airtight chamber of manned spacecraft may emit toxic gas in different rate and concentration. In this paper, some typical nonmetallic materials are chosen for low-pressure outgassing experiments, and the effects of the outgassing volume and rate under different low-pressure conditions are studied. |

| Keywords: | nonmetallic materials low pressure outgassing sealed cabin environmental control |
