热机循环极限效率的图像讨论法

A discussions on the maximum cycle efficiency by using graphics

证明了在相同的高温热源和相同的低温热源之间的所有可逆循环中,卡诺循环的效率最大;而采用T-S图和p-V图的方法对此进行讨论,则是一种简明直观的方法.

It is proved that for all the reversible prosses between the heat sources of the same high temperature and low temperature,the Carnot cycle has the maximum efficiency.The discussion uses T-S diagram and (p-V) diagram method,which are more simple and intuitive.
