| 摘 要： | 随着经济快速发展,城市高层建筑日益增多,人们活动空间增至到距离地面40m～100m高处,因此大气垂直空间的颗粒物污染状况日益受到人们的关注.就此,进行了可吸入颗粒物质量浓度、粒度的垂直分布研究,得到了可吸入颗粒物在垂直空间中的分布规律,建立了PM10随高度分布的回归方程,并对不同高度的浮尘样品进行粒度分布研究,进一步验证了PM10随高度增加细粒子含量增加的垂直分布规律.

| Abstract: | Along with the rapid development of economy and the increase in the high buildings in the city, the activity space of people has risen to 40m - 100m from the ground, so there is a wide concern among people about the situation of the particle pollution of the atmosphere vertical space. The paper studies the vertical distribution of the quality density and particle size distribution of the inhalable particles, obtains the distribution law in the vertical space of the inhalable particles, establishes the regression equation of the PM10 distribution with the height, studies the granularity distribution of the floating dust samples in different height and further validates the vertical distribution law of PM10 increasing with the height as the content of the fine particles increase at the same time. |
