本文给出了用温熵图证明卡诺定理的更直观更简单的方法 并通过实例证明采用温熵图处理某些热力学问题得出结论的过程也比使用P - V 图或常用的热力学方法更为直观、方便。-In this paper, with a temperature entropy diagram of Carnot theorem proved simpler and more intuitive way　and through examples demonstrate some of the thermodynamic temperature and entropy map processing a conclusion of the process than using the P- V diagram or thermodynamic method commonly used more intuitive and convenient.
