熵函数引出之我见

A NEW DEDUCTION APPROACH TO ENTROPY FUNCTION

本文叙述了熵函数几种推导方法及各种推导方法的特点。指出一般物理化学教本中沿用卡诺循环的方法原理去推导熵函数不一定是最好的方法。笔者认为用从热力学第一定律的方法去推导熵对认识熵较为深刻,是推导熵的好办法。而且物理意义明确,还可避免繁杂的数学演算。

Som deduction approaches of entropy function and its variety characteristics are presented and reviewed. This paper also points out that the carnot cycle which was quoted in several textbook of physical chemistry is not a good method to infer entropy function. It shows that it is a better method, which has the definite physical meaning and avoids the complicated mathematical inference, to deduce entrooy function from the first law of thermodynamics.
