小孔泄流速度分布与麦克斯韦速度分布的关系

Holes Velocity Distribution and Relationship of Maxwell Speed Distribution

推导泻流分子的速度分布,讨论泻流速度分布与平衡态分子麦克斯韦速度分布的关系,并将它们的速度分量的分布、速率分布作了对比。泻流分子的分布律与容器内气体分子的分布具有一定的对应关系,但二者是有区别的。

The velocity distribution of effusion derived molecules, discuss purging flow velocity distribution relationship with the equilibrium molecular Maxwell speed distribution, and the velocity distribution of quantity distribution and velocity distribution. Effusion molecular distribution law and container distribution has a certain corresponding relationship of gas molecules, but there is a difference between the two. Key words： effusion; speed distribution; velocity distribution; velocity component distribution
