卡诺定理的一种直接证明方法

A method of direct demonstration of Carnot theorem

目前普通物理学、热力学及热统教材中,证明卡诺定理多采用反证法。本文给出了由热力学第一定律 和热力学第二定律直接证明卡诺定理的一种方法。

Most of present physics teaching materials, such as Common Physics, College Physics, Thermodynamics,Thermodynamics and statistic physics, always take counterevidence to prove Camot theorem. This article points out Carnort theorem also can be proved directly thought the first and second law of thermodynamics and provides a direct demonstration
