在牛顿传热律下，考虑了斯特林致冷机中热阻的不可逆性和回热损失的不可逆性，利用生态学准则函数Ｅ，研究了致冷率与熵产生率协调的整体优化性能，导出了致冷率Ｒ与致冷系数ε的优化准则，并对最佳输入功率，回热损失等其它性能进行了优化分析与讨论，为斯特林致冷机的优化设计以及最佳工作状态的选择提供了一种新方案。

In Stirling refrigerator, the nonreversibility of thermal resistance and the nonreversibility of regeneration loss for Newton's heat transfer law is considered, the whole optimum performance with the refrigeration rate in cooperation with the entropy production is investigated, by using the ecological critertion function E, the optimum critertion for refrigeration rate R and performance coefficient ε are derived, and the other optimum performances for the optimal input power and the regeneration loss, etc. are discussed, which provides the new plan for the optimum design and the selection of optimal operating condition of Stirling refrigerator.
