Theoretical analysis indicate that when the thickness of the film materials is equivalent to the average free path of the electron, the transmission depth of the heat radiative wave can be increased effectively by reducing the film material thickness so that the heat radiative characteristics of the film mat.
理论分析表明 ,当薄膜材料的厚度与电子的平均自由程相当时 ,减小薄膜材料的厚度可以大幅度提高热辐射穿透深度 ,从而显著地改善薄膜材料的热辐射性能。

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。

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.
