摘要
首先对输运过程中穿过参考截面△S的气体分子自由程的平均值穿为什么不等于而是大于作出了定性解释,然后通过定量计算求出了穿=2。
At first,a kind of qualitative explanation why the mean free path of molecule(穿) passing through a certain reference section in the course of transportation is not equal to but larger than is brought forward,and then,穿=2 is worked out by means of quantitative calculation.
