初学物理化学的同学们对于熵和过程的不可逆性等概念常常不很清楚。对于这一问题早想把我在教学工作中得到的一些体会写出来和大家讨论,最近看到Л.З.列文所写的题为“熵与过程的不可逆性的程度”的文章,对这问题作了讨论和分析,但他的观点和我所想的不尽相同,且其中有些名词是容易发生混淆的,有些提法是值得商榷的,因此把我的意见写出来,希望得到同志们的指正。
New-year students of physics and chemistry are often not very clear about the concepts of entropy and the irreversibility of the process. As early as this question I would like to write down some of the experiences I have gained in my teaching work and discuss it recently. I recently read the article entitled “The extent of entropy and the irreversibility of the process” written by L. Levin in This issue has been discussed and analyzed. However, his point of view is different from what I think. Some of the terms are easily confused. Some of the formulations are debatable. Therefore, I should write down my opinion and hope to get gay They are correct.
