摘要
文章聚焦于中国空间站长期在轨运行中微量有害气体的整体状态和控制情况,阐述了微量有害气体随舱内物质循环向冷凝水回收净化以及CO_(2)去除和还原等环节流转的规律。通过在轨状态分析、地面比对评估试验结果和流转特性分析,说明中国空间站各净化系统对舱内微量污染物成分进行了有效控制,舱内空气中微量有害气体浓度保持在较低水平。研究旨在为后续微量有害气体净化环节的运行和监测提供指导。
Focusing on the general status and controling of trace contaminants in China Space Station(CSS)during long-term in orbit flight,this article describes the transferring characteristics of trace contaminants carried by the substance circulation in the cabin to the humidity condensation and purification,as well as to the CO_(2)removal and reduction subsystem.On-orbit status analysis,comparison of ground evaluation test results and circulation characteristic analysis all show that air-purification subsystems provide effective controling of trace contaminants,and the concentration of trace contaminants in the cabin is maintained at a low level.The study may provide a guidance for the future operation and monitoring of contaminant purification in CSS.
