航天员长期在轨的密封舱内出气产物成分监测对比分析

Comparative Analysis of Monitoring the Composition of Exhaled Products in Sealed Cabins of Astronauts in Orbit for a Long Time

首先试验研究了航天员长期在轨的密封舱内部组件出气产物成分,利用气相色谱质谱仪(GCMS)和高效液相色谱仪(HPLC)对航天员长期在轨的密封舱内部组件出气产物成分进行了分析,进而探讨了航天员长期在轨的密封舱内部组件出气产物成分随时间增加的变化机理。研究发现,部组件的脱出有害物质成分总量随时间增加而增加,日均释放量在释放达到平衡后随时间增加而减少,扩散平衡是主要原因。

Firstly,an experimental study was conducted on the composition of outgassing products from internal components of sealed cabins in which astronauts have been in orbit for a long time.Gas chromatography-mass spectrometry(GCMS)and high-performance liquid chromatography(HPLC)were used to analyze the composition of outgassing products from internal components of sealed cabins in which astronauts have been in orbit for a long time.Furthermore,the mechanism of changes in the composition of outgassing products from internal components of sealed cabins in which astronauts have been in orbit for a long time was explored.Research has found that the total amount of harmful substances released from some components increases with time,and the daily average release decreases with time after reaching equilibrium,with diffusion equilibrium being the main reason.
