摘　　要：基于有限时间热力学理论，以可使热力循环的功能率与功能率耗散达到最佳折衷的生态学准则为目标，研究受热阻和回热损失等不可逆因素影响的斯特林热机优化关系，探讨一类二热源热机优化关系的统一表达式，并作讨论．Based on finite time thermodynamic theory,the optimal performance of a class of Stirling heat engine affected by thermal resistance and regenerative losses is studied by using an objective function of ecological criterion.Some new performance parameters of the Two-Heat-Source Engine are derived.They provide a new plan for the selection of optimal operating condition and have instructive significance for the optimal design of the Heat-Engine.
