摘要
大气颗粒物是环境在线监测的一个热点,研究表明,颗粒物是导致能见度退化、引起区域灰霾现象的主要原因。为了有效降低大气颗粒物中的水汽对称重结果的影响,介绍了一种新型振荡天平使用及计算方法,振荡天平采用平衡称重室与实时称重室并行称重,并利用平衡称重室的测量结果对实时称重室进行校正,可使测量结果更准确。
Atmospheric particulate matter is a hot spot in environmental on-line monitoring.Research shows that particulate matter,especially fine particulate matter(such as PM2.5),is the main cause of regional haze.This paper mainly introduces a new type of oscillatory balance and its calculation method.Oscillating balance performs the parallel weighing by both balanced weighing chamber and real time weighing chamber and uses the result of the former chamber to rectify that of the latter chamber to ensure the accuracy through effectively reducing the influence of aqueous vapor in particulate matters on weighing results.
