摘　　要：本文采用大流量采样、β-射线衰减测尘仪与TEOM测尘仪分析测定空气中的总悬浮颗粒物,对比实验结果表明:TEOM法与经典大流量测定方法、β-射线衰减法测量结果均具有可比性,TEOM法与大流量法更具有一致性.TEOM法测量精度较高。There are three kinds of developing measurements of ambient TSP: high vacuum sampling, β-Gauges monitor and tapered element oscillating microbalance monitor. Comparative experiment result show that the result of TEOM is comparable with high vacuum sampling and β-Gauges monitor respectively. TEOM monitor is unanimous with high vacuum sampling. Precision of TEOM monitor is the highest, TEOM monitor is more fit for on-line ambient air quality monitoring than the other TSP monitor.
