本文从实验上验证了斯特林循环的效率与卡诺循环的效率一致.实验结果和理论分析表明,工作物质在等体过程中吸收的热量无须计入循环效率的计算公式,因为斯特林循环中的回热器是在系统内部与工作物质进行热量的交换,对外界没有影响.%In this paper,we experimentally verified that the efficiency of Stirling cycle is equal to the efficiency of Carnot cycle.The result shows that the heat transformation in the isochor-ic processes need not be considered in the efficiency formula,because the heat transformation of heat regenerator is inside the Stirling engine,which has no influence on the surroundings outside.
