摘　　要：检测空气中悬浮颗粒物的粒径分布及浓度是当前环境保护部门的重要工作,这两个参数直接反映了当前空气的质量.论文介绍的一体化测量系统,能对采样的气体同时进行粒径分布和悬浮颗粒物质量浓度的测量.由于是对同一气体同时进行测量,因此能准确反映被测区域的空气质量,并且给测量带来方便.实测表明:使用本测量系统的测量结果与用传统的单功能测量仪器测量的结果差别不超过±5%.这种测量方法目前在国内尚未见报道.It＇s important to the environmental protection department to measure particle size range distribution and concentration of suspended particle in air. These two parameters indicate the quality of air directly. The integrated meter mentioned therein measures particle size range distribution and mass concentration simultaneously using the same one sample, which makes more convenient and more precise. The difference between the data getting from the integrated system and the data getting from traditional single- function meters is less than 5 %. The method mentioned therein is not reported before.
