摘　　要：大气气溶胶的气候效应、环境效应、健康效应均与其物理化学性质密切相关,其中,密度是大气气溶胶重要的物理性质之一。密度影响着粒子的输送过程和在人体肺部的沉积过程。密度可以分别将电迁移率粒径和空气动力学粒径,数浓度和质量浓度联系起来。密度的变化可为气溶胶的形成和老化过程提供信息,细粒子分粒径的密度还可为大气过程和化学组分的演化提供参考依据。因此,研究大气气溶胶密度对了解气溶胶化学组分,评估气溶胶形成过程以及探究气溶胶在人体内的沉积效率具有重要的意义。由于国内在该领域研究总体较少,对大气气溶胶密度的定义、研究方法、国内外研究进展以及影响因素和变化特征等进行较为系统的总结,对未来开展大气气溶胶密度的观测和研究十分必要。The effects of atmospheric aerosols on climate,environment and health are closely related to their physical and chemical properties. The aerosol density is one of the most important physical properties of atmospheric aerosols. Density affects the transport of particles and the deposition process in the lungs of the human body. Besides,density can associate mobility diameter with aerodynamic diameter,number concentration with mass concentration respectively. In addition,the time series of density can provide information on the formation and aging process of particles. What’s more,size-resolved density of fine particle can also provide reference for atmospheric process and chemical composition. Therefore,the study of atmospheric aerosol density has a very important significance to understand chemical composition of aerosols,to evaluate the formation of aerosols and to explore the deposition efficiency in the human body. This paper systematically reviewed the definition,research methods,domestic and foreign research progress,influence factors and variation characteristics of atmospheric aerosol density. Since there are few studies have ever taken in China in this field,it is necessary to carry out more research on the measurement of density of atmospheric aerosols widely.
