摘要:
一次颗粒物的粒径分布及化学组分等对雾霾形成和健康具有显著影响.为了认识一次颗粒物的粒径分布,本文基于颗粒物相关理论计算,研制了一套颗粒物再悬浮分级采样装置,并对其运行稳定性进行了评价.结果表明,对TSP、PM10、PM2.5样本质量进行方差分析,所得F值分别为0.42、0.07和1.34,远远小于F0.95(2,17)=3.59;对PM10占TSP比重、PM2.5占PM10比重进行方差分析,F值为0.53,远远小于F0.95(9,19).说明颗粒物在再悬浮腔体中能够均匀分布,该颗粒物再悬浮采样装置可以满足一次颗粒物的分级采样.

Abstract:
Particle size distribution and chemical composition of the primary particles have significant influences on the formation of haze and human health. In order to understand the size distribution of the primary particles, a resuspension sampling device had been developed which was based on the calculation of particle correlation theory. The stability of the device was evaluated. The results indicated that:The quantity of TSP, PM10 and PM2.5 samples were analyzed by variance analysis. F values were 0.42、0.07 and 1.34 and far less than F0.95(2,17). The variance analysis of PM10/TSP and PM2.5/PM10 was conducted, respectively. F value was 0.53 which was far less than F0.95 (9, 19)=3.59. The results demonstrated that the particles could be uniformly distributed in the resuspension cavity. The sampling device was able to satisfy the requirement of size classification of primary particles.
