摘要： 指出引进热力循环生态学品质因数的主要目的,是要使热力循环的功能率与功能率耗散达到最佳的折衷,因而它必须基于普遍的生态学准则函数来建立.而基于分析生态学目标函数所建立的生态学品质因数,在许多场合下是不适用的.此外还讨论了生态学品质因数的重要意义和应用.

关键词: 有限时间热力学, 生态学品质因数, 热力循环

Abstract: It is pointed out that the main purpose of introducing the ecological figure of merit of a thermodynamic cycle is to make the best compromise between the rate of function and its dissipation of the cycle. Thus, the ecological figure of merit of a thermodynamic cycle should be based on the general ecological criterion function, while that based on the objective function of exergy analysis is not applicable in many cases. The significance and application of the ecological figure of merit are also discussed.

Key words: finite-time thermodynamics, thermodynamic cycle, ecological figure of merit
