用麦克斯韦速度分布律探讨粒子的速度分布函数

The Discussion of particle's Velocity Distribution Function by the Law of the Maxwell's Velocity Distribution

本文叙述了麦克斯韦速度分布律的适用范围,用麦克斯韦速度分布律分别探讨了气体分子的三维、二维和一维运动时的速度分布函数,并讨论了等离子体的带电粒子在均匀磁场中的速度分布函数。文章拓展了学生对麦克斯韦速度分布律的理解,有利于培养学生用课本知识解决实际问题的能力。

This article introduces the scope of the law of the Maxwell''s velocity distribution. The law of Maxwell''s velocity distribution is used to discuss the velocity distribution function of gas molecules in one dimension, two dimensions, and three dimensions, respectively. The velocity distribution function of charged particles of plasma in uniform magnetic field is also demonstrated. The students can further understand the law of the Maxwell''s velocity distribution. Thus, it can help the devel-opment of resolving the actual problem based on the learned knowledge.
