中文摘要：

应用有限时间热力学方法和生态学优化准则对不可逆布雷逊热机循环的各种性能参数进行优化，导出了服从牛顿传热规律并考虑热阻、热漏和内不可逆性的布雷逊热机循环在生态学目标函数最大时输出功率和效率的表达式。讨论了热漏、内不可逆性对该热机各种性能参数的影响，同时还比较了最大输出功率和最大生态学目标函数下该热机各种优化性能参数间的关系。所得结果给实际热机的优化设计提供了理论依据。

英文摘要：

A performance optimization based on the ecological criterion was carried out for a generalized irreversible Braysson heat engine. After considering heat-resistance, heat leak, and internal irreversibility the expressions of power output and efficiency of the generalized irreversible Braysson heat engine obeyed the Newton＇s heat transfer law were derived at the maximum ecological objective function. The influence of heat leak and internal irreversibility on the performance parameters of this engine was discussed. The results obtained here provide some significant guidance for the optimal design and operation of the practical heat-engine.
