摘　　要：为探讨对载人航天舱内空气污染进行监测的采样方式，本文通过对甲苯－空气混合气的扩散采样的定量研究，提出了扩散采样定量方法、步骤及其方法的有效性，讨论了环境因素对采样定量的影响。本方法对多组分有害气体－空气混合气的扩散采样定量有参考价值。The diffusive samplig is of great advantage to air pollutant monitoring in manned spaceflight cabin. The quantitative method and steps of diffusive sampling is given in this paper by an experimental studying on diffusive sampling of toluol-air mixture;Effectiveness of the method and effects of environmental factors on the quantification of the diffusive sampling were discussed.This method is of reference value to quantification of the polycomponent-air mixture.
