摘　　要：近年来,随着城市建设和经济的发展,气溶胶颗粒物污染问题日益严重,尤其是城市浓雾天气,颗粒物成为首要污染物.因此,消除雾污染,净化空气,引起人们的关注.介绍了气溶胶颗粒物和雾的基本特征,以及雾层内气溶胶颗粒物的湍流扩散、化学转化特性及动力学特性,阐述了有关气溶胶颗粒物输运问题的国内外研究概况,展望了未来研究的方向.In recent years,with the urban construction and economic development,the problem of aerosol pollution is becoming increasingly serious.Especially for foggy weather in urban areas,aerosol particles form a primary pollutant.This calls for people＇s concern to deal with the fog pollution problem for clean air.This paper focuses on the basic characteristics of aerosol particles and fog,including turbulent diffusion of aerosol particles,chemical transformation and dynamical characteristics.In addition,a detailed investigation on the aerosol transport problem in China and other countries is made,and the direction of the studies is discussed.
