一、引言 经典热力学追求热机的高效率,得到了可逆效率界限ηC=1-T_L/T_H,式中T_H、T_L分别为热机高、低温热源温度。有限时间热力学强调输出功率和效率的协调,得到了有限时间热力学性能界限ηCA=1-(T_L/T_H)~(0.5)、优化关系和参数选择准则。本文则在文献[7] I. INTRODUCTION Classical thermodynamics pursues the high efficiency of the heat engine and obtains the reversible efficiency limit ηC = 1-T_L / T_H, where T_H and T_L are the high and low temperature heat sources respectively. The limited time thermodynamics emphasizes the coordination of output power and efficiency, and obtains the limit of thermodynamic performance ηCA = 1- (T_L / T_H) ~ (0.5), the optimization relation and parameter selection criterion.
