摘　　要：本文从熵的定义和基本性质入手,首先引入T—S图计算卡诺循环的效率,其次利用dS/dV分析经历p=aVb+m过程的理想气体的吸热或放热情况,最后运用上述结果求解了一个特殊热力学循环的效率.Based on the definition and basic properties of entropy, the efficiency of Carnot cycle is calculated by T-S diagram, and the decalescence or radiation of ideal gas in the process of p=aV^b-m are analyzed by dS/dV. Finally, the efficiency of a special thermodynamic cycle is solved by making use of the results above.
