INFLUENCE OF CHARGE FLUCTUATION ON DUST MAGNETOACOUSTIC WAVE IN SPACE DUST PLASMA
-
摘要: 本文运用自洽的三流体方程组, 考虑了尘埃的充电过程, 得到均匀磁化尘埃等离子体中垂直于磁场传播的尘埃磁声波的色散关系, 结合空间环境讨论了尘埃电荷的相关涨落对尘埃磁声波的影响.Abstract: Charging processes of dust gndns in plasma are analyzed. Aset 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.
