为对载人密闭舱的有害气体进行分析和评价 ,本实验模拟飞行状态 ,对密闭舱内有害气体进行了 5d的跟踪检测和分析 ,定量出 8个有机类别共 82种挥发性有机化合物(VOCs)和三种目标无机物 ,探讨了气体成分的变化规律 ,并对密闭舱大气质量进行了初步的毒性评价 ,可供座舱大气质量的监测与评价参考。
In order to analyze and evaluate the harmful gases in the airtight manned compartment, the experiment simulated the flight status, conducted the 5 days follow-up detection and analysis of the harmful gases in the airtight compartment, and quantified a total of 82 volatile organic compounds (VOCs) ) And three kinds of target inorganic matter. The gas composition variation was discussed. The air quality of the airtight chamber was preliminarily evaluated for its toxicity, which could be used as a reference for the monitoring and evaluation of the cabin air quality.
