摘要
本文由熵的定义和温熵图得到含二绝热过程和二同类多方过程的这样一类特殊循环过程效率的简洁表达式.结果表明,该类循环的效率形式上与卡诺循环的效率完全相同.
Based on the definition of entropy and the T-S diagram,the concise expression of efficiency for a special cycle consisting of two adiabatic processes and two similar polytropic processes is obtained.It is shown that the form of the efficiency for such a kind of cycle is the same as that of Carnot cycle.
