摘　　要：超低排放条件下的污染物测试,普遍具有染物浓度低、烟气湿度大、含有酸雾气溶胶、测孔位置布置不规范等特点,超低排放条件下烟尘、PM2.5的高精度测试一直是近年来研究的热点和难点,对国内外相关测试标准进行梳理和分析,探讨了测试精度的控制方法,提出了超低排放条件下烟尘、PM2.5测试方法,通过现场实测验证了该方法的准确性,可为相关测试标准的修制定提供技术支撑。There are generally test characteristics under the condition of ultra-low emission,such as low dye concentration,flue gas high humidity,contain acid mist aerosol and measuring hole location layout is not standard.The high precision testing of PM/PM2.5 under the condition of ultra-low emissions has been a research hot spot and the difficulty in recent years.In this paper,relevant test standards at home and abroad was analyzed,the test precision of the control method was discussed,PM/PM2.5 test method under the condition of ultra low emission was put forward,and the accuracy of the proposed method was verified by field testing,which can provide technical support for relevant test standard.
