环境空气和废气颗粒物的测量不确定度评估

Assessment of Measurement Uncertainty for Ambient Air and Exhaust Gas Particulate Matter

为了探寻环境空气检测中废气颗粒物测量工作的影响因素,本文在实验中,对废气颗粒物中典型的PM_(2.5)和PM_(10)两种物质展开了检测,并根据检测结果对其不确定度进行了评估。同时,通过本次测量不确定度评估分析工作,得出了在环境空气废气颗粒物测量中主要误差的影响因素,从而为后续的测量试验工作提供更多的优化参考方案。

In order to explore the influencing factors of exhaust gas particulate matter measurement in ambient air detection,in the experiment in this paper,the two substances typical PM_(2.5) and PM_(10) in exhaust gas particulate matter are detected,and the uncertainty is evaluated according to the test results.At the same time,through this measurement uncertainty evaluation and analysis work,the main error influencing factors in the measurement of exhaust gas particulate matter in ambient air are obtained,so as to provide more optimization reference scheme for the follow-up measurement test work.
