摘要： 应用有限时间热力学理论,首先对内可逆卡诺热机的传热温差进行优化分析,并讨论了最佳温差的几种备选方案.进而分析热阻外其它不可逆性对最佳温差的影响,获得一些对实际热机更有指导意义的新结论.

Abstract: Using the theory of finite-time thermodynamics, the optimal temperature difference for heat-transfer of an endoreversible Carnot engine is analysed,and several plans for the choice of optimal temperature difference are discussed.Then, the effects of other irreversibilities, except thermal resistance, on the optimal temperature difference are analysed. Some more instructive new conclusions for the practical heat engine are obtained.
