摘　　要：综合复压系统是载人航天器空间环境试验设备的关键系统之一。文章结合国内外载人飞船试验的经验,简要介绍了载人试验舱综合复压系统方案设计时应考虑的主要技术指标。响应时间和阀门的选择是复压系统正常工作的关键；使用气体混合仪对氧、氮比精确控制以使复压气体符合航天员的生理要求。对复压流程进行了仿真,结果表明复压系统的设计能满足紧急复压的要求。Repressurization system is one of the crucial systems of space environment simulator for manned spacecraft test Some of the main technology indexes,such as repressurization velocity and repressurization gas control,are introduced.As the key equipments of the system,the valves and the gas mixing equipment are introduced in detail.The emulation results of repressurization flow show that the design of the repressurization system meets the requirement of urgency repressurization.
