摘要
研究与制订大气环境质量标准，即确定和评价大气中污染物浓度与暴露时间的影响、损害作用及彼此的相互关系乃是环境保护的重要研究课题。本文建议统一采用“标准状况下，标准组成干燥空气中所含污染物浓度”的严格概念。同时，还研究了大气采样中由于现场条件与大气成分不同所产生的气体流量（率）计量误差，得到了这种误差的一般数学表达式。
To Study and establish Ambient Air Quality Standards ie.To determine and impact the effects,injury and interact each other of pollutants concentration and exposure time is imporctant environmental protection objective. The articl e proposes employing entirely rigorous conception in expressing pollutants concentration, ie pollutants concentration at normal condition and standard constituent in dry atmosphere.Besides,it had been considered an atmosphere Sampling error arising from effect of different plant condition and constituent during sampling period for atmosphere flow measure. The equation is obtained mathecatically.
