不可逆扩散过程的微观实质

The Micro-substance of Irreversible Diffusion Process

根据等概率原理,通过对宏观气体异扩散前后微观状态数的计算,得出宏观气体异扩散的微观实质是扩散后宏观状态出现的概率远远大于扩散前宏观状态出现的概率。

Through computing microstate numbers of macro-gas before and after its space-variant diffusion, based on the equal probability principle, we conclude that the micro-substance is more likely to occur after the space-variant diffusion of macro-gas than before its diffusion.
