摘　　要：舱外航天服是航天员完成出舱活动的必要装备,为了确保出舱活动的顺利进行以及航天员的生命安全,针对舱外航天服的试验舱的设计与测试至关重要。本文根据航天试验的需要,设计了空间环境试验舱的液氦系统,并通过调试试验,对液氦系统的性能进行测试,表明该液氦系统完全可以满足技术要求。It is crucial to an astronaut that he must be in special space suit when working out of the space capsule to keep him safe. So, the design of an interrelated space simulator is very important to testing the suit. A liquid helium system of the space simulator was therefore designed to meet the need of astronaut＇s activities for space exploration and its performance was tested. The results showed that the helium system can completely meet the technical requirements.
