CHARGE FLUCTUATION AND ELECTROSTATIC WAVES OF DUST PLASMA IN COMETARY ENVIRONMENT
-
摘要: 本文分析了尘埃等离子体中尘埃颗粒的带电过程,给出了一套自洽的工流体方程组.运用这组方程研究了尘埃电荷的起伏涨落,得到了非磁化均匀尘埃等离子体中静电波动的色散关系.针对彗星空间环境中尘埃等离子体的特点,讨论了尘埃电荷的涨落对各种静电波动的影响.Abstract: In this paper, charging processes of dust grains immersed in plasma are analysed.A set of self-consistent three-fluids equations are given for dust plasma. From theseequations, fluctuation of charge on dust gtaln is studied and dispersion relations arederived for electrostatic waves in a unmagnihzed dust plasma. The influence of chargefluctuation on electrostatic waves is discussed for space dust plasma
