本文建立太阳能热机系统的一般循环模型，探讨传热和内不可逆性因素对其循环性能的影响，在不同的热传递规律下优化系统的各主要性能参数，对系统的效率、集热器的工作温度和热机中高、低温热交换器的传热面积比作了较深入的分析，从而获得一些有意义的新结论。
A general cycle model of a solar engine is set up.The influence of finite-rate heat transferand internal irreversibility on the cyclic performance of the system issearched. The several main performance parameters of the system areoptimized for some different heat-transfer laws. The efficiency of thesystem, the operating temperature of the solar collector and the ratioof heat-transfer areas of heat exchangers in the engine are analyzed indetail, so that some new significant results are obtained.
