摘要
麦克斯韦速率分布函数在分子动理学的平衡态理论中具有重要的意义。文章从麦克斯韦速率分布函数f(v)的基本涵义出发,详细讨论了由分布函数f(v)演变出的物理函数意义,并重点讨论了利用f(v)dv函数求平均值时的积分区间问题,对个别易犯的物理本质上的错误进行了纠正。
Velocity distribution function for Maxwell is important in the equilibrium theory of molecular dynamics. Began from the basic meanings of velocity distribution function f (v) for Maxwell, some physical functions derived from the distribution function f (v) are discussed in detail. This paper focuses on the discussion for the integral interval problem when the average values of some physical variables are performed with making use of the function f (v)dv, and corrects individual errors which are easy to commit in physical essence.
