摘要
本文利用参与定向运动动量输运的分子数是总分子数的16的假设,综合通过考虑分子的速度分布及分子从各个方向穿过dA面,阐述了一种既严格又简明计算输运过程无碰撞地穿过dA面的分子之平均自由程方法。
A method of calculating the average free path of molecules punching the cross - section dA without collision on the process of transport is proposed on the basis of assuming that the number of molecules participating the directional locomotion momentum motion are 1/6 of the total ones in the paper. The method is characterized by its simplification and rigor.
