| Abstract: | The charging mechanism and wave process in dust plasma as well as some related phenomenoin the space physics of the solar system are reviewed and discussed. This paper deals withequilibrium electric potential on the surface of the dust grain, action on charging dust andinduced motion in the space, erosion of planetary rings on their inner edge, formation of spokes,electrostatic disruption of cometary dust, evolution of cometary dust tail, stobility of Neptunesring and so on. |
