摘　　要：基于β射线法原理,提出了TSP、PM_(10)、PM_(2.5)平行采样的大气颗粒物分级监测系统的结构形式与控制方法。通过对β射线法粉尘浓度计算方法、纸带精确位移技术以及抽尘管道动态加热结构的研究,研制出了大气颗粒物分级监测系统。通过与标准称重法对比实验,该系统TSP、PM_(10)及PM_(2.5)的相关系数分别为0.993、0.989和0.986,实现了大气颗粒物的高精度分级监测。Based on the principle of β-ray method,the paper proposed the structure and control method of atmospheric particulate classification monitoring system for parallel sampling of TSP,PM（10） and PM（2. 5）. Through the research of calculation of the β-ray dust concentration method,the precise displacement tape technology and dust exhaust pipeline dynamic heating on the structure,the classification monitoring system for atmospheric particles was developed. Compared with the standard weighing method,the correlation coefficients of TSP,PM（10） and PM（2. 5） were 0. 993,0. 989 and 0. 986,respectively. High precision was realized in terms of atmospheric particulate matter monitoring.
