Abstract

The significant advances are made in the mechanics of aerosol since the w ork of the great Russian scientist named Fuchs in 1964.T he study on aerosol dynamics is carried forw ard from the stage of isolated particle of Fuchs time to the stage of multiparticle interacting of present time.T his progress is summarized and the stress on sedimentation and coagulation of small particles is put in this paper.

Keywords：aerosol dynamics； pair-distribution function；sedimentation；coagulation
