摘要/Abstract

摘要： 该文用随机动力学理论研究等离子体中难熔粒子的运动行为。建立了分布函数所满足的Kolomogorov方程。在一维半无限空间和反射边界条件下求解了该方程,结果与现有的实验事实相吻合。

Abstract: The motion behaiviour of difficult-to-melt particle immersed in plasma. is studied with stochastic dynamics in this paper. The Kolmogorov equation is presented and solved under reflecting -boundary condition in one-dimension half infinite space. The result conforms to the experiment data obtained at present.

Key words: langevin equation, probability distribution, knudsen number
