| Abstract: | Charging processes of dust gndns in plasma are analyzed. A set of self-consistenttaewflulds equahons are given for dust Plasma. From these equaons, fluctuation ofcharge on dust grain is stUdied and dispersion relations are derived for dustmagnetoacoustic waves in magnehzed dust plasma The influence of charge fluctuationon dust waves is discussed for some dust plasma in space. |
