摘　　要：β射线法颗粒物在线监测仪系统具有使用方便、数据可靠和维护成本低等优点。在介绍该仪器基本原理的基础上,将手工颗粒物采样器与β射线法颗粒物在线监测系统进行同步比对测试。测试结果表明,该分析仪性能稳定,测定的环境空气中PM10浓度数据相对误差低于±10%,能够满足大气颗粒物监测的需求。β射线法颗粒物在线监测仪为大范围空间颗粒物质量浓度的监测提供了一种快速、实时的手段。The β-ray particle on-line monitor system has the advantages of easy operation, reliable data and low maintenance cost. On basis of introducing the basic principle of the instrument, manual particle sampler is compared with β-ray particle online monitoring system. The i-results show that the analyzer has stable performance, and the relative error of PM10 concentra tion in ambient air is less than β- 10%, which can meet the demand of monitoring atmospheric particulates. The β-ray particle on-line monitor provides a fast and real-time means for monitoring the mass concentration of large space particles.
