The "free path" of a gas molecule appeared in the kinetic theory have two meaning: one is the distance through which a molecule flies between two successive collisions, the other is that a molecule flies from the observing moment to the first collision moment.
在分子运动论中,“自由程”有两种含义,一种是一个分子在相继两次碰撞之间飞过的路程,另一种是它从观察时刻到之后的第一次碰撞时刻飞过的路程。
