摘　　要：以反映热机功率与熵产率之间最佳折衷的"生态学"准则为目标,综合考虑热阻、热漏及内不可逆性的影响,导出了传热规律服从Q∝(ΔT)n时不可逆热机生态学最优性能,对n=1和n=1.25的2种典型传热规律进行了进一步讨论,该文结果对实际热机的设计工作具有一定的理论指导意义.Considering the effect of heat leak and internal irreversibility the optimal ecological performance of a generalized irreversible Carnot engine with the heat transfer law of Q∞(ΔT)n, is derived by taking an ecological optimization criterion as the objective, which consists of maximizing a function representing the best compromise between the power output and entropy production rate of the heat engine. Some special examples for n=l and n=1. 25 are discussed. The results can provide some theoretical guidance for the design of practical engine.
