应用数值方法，分析并讨论了热机在最大输出功率、最大效率和最大生态学函数下的优化循环性能特性。
By using numerical solution method, the optimal cycle performance characteristics of the engine at maximum power output, maximum efficiency and maximum ecological function are analyzed and discussed.
获得了在最大生态学函数条件下的最佳效率、输出功率和熵产生，并与在最大输出功率条件下的结果进行比较。
The optimal efficiency, output power and entropy production at the maximum of an ecological function are obtained, and are compared with those results at the condition of maximum output power.
导出了该模型下输出功率、效率和生态学目标函数的表达式。
The analytical expressions of power output, efficiency and ecological objective function are derived.
因此，生态学目标函数不仅反映了输出功率和熵产率之间的最佳折衷，而且反映了输出功率和热效率之间的最佳折衷。
So it represents not only a compromise between the power output and the entropy generation rate but also one between the power output and the thermal efficiency.
