两种PM_(10)观测仪器数据对比分析

Comparative analysis on the data between two PM_(10) observation instruments

文章介绍了β射线法和微量振荡天平法2种PM_(10)质量浓度观测仪的原理和观测方法,并通过对北京2016年的数据对比分析,得出两种观测法测得的PM_(10)质量浓度差距与空气湿度和地面风速的大小相关,观测结果也因观测原理和加热方式的不同产生差异。

This paper introduces the principles and observing methods of PM10 mass concentration observation instruments based on β ray and taper element oscillating microbalance two methods.According to comparative analysis on the data in 2016 Beijing,the differences of PM10 mass concentration observed by the two methods is related to the air humidity and ground surface wind speed.The observation results differences can be made by using different observing principles and heating manners.
