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、热漏及工质内不可逆性,导出了线性唯象传热规律下不可逆卡诺热机的生态学最优性能,该结果对实际热机的设计工作具有一定的理论指导意义.The optimal ecological performance of a irreversible Carnot engine with the losses of another linear heat-resistance, heat leak and internal irreversibility 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. The results can provide guiding sense for designing a practical engine.
