摘　　要：考虑高低温侧换热器、回热器和中冷器的热阻损失,以功率为优化目标,对恒温热源条件下内可逆闭式布雷顿循环的高低温侧换热器、回热器和中冷器的热导率以及中间压比的分配进行了优化。借助数值计算,分析了一些主要循环特征参数对最大功率及相应热导率和中间压比分配、双重最大功率的影响。The heat resistance losses of working mediums in high and low temperature side heat exchangers, regenerative heaters and intercoolers have been taken into account for an endoreversible closed Brayton cycle under constant temperature heat source conditions.With power output serving as an objective of optimization the authors have optimized the distribution of thermal conductivity values and intermediate pressure ratios for the above mentioned items. Through the use of numerical calculations analyzed is the impact of several main cycle characteristic parameters on the distribution of maximum power, corresponding magnitudes of thermal conductivity, intermediate pressure ratios and the double maximum power.
