摘　　要：建立一类较普遍的不可逆斯特林热机模型,研究存在热阻、热漏、回热损失时斯特林热机的优化性能,导出了热漏损失服从一般传热规律时热机的功率与效率间的优化关系,从而可为二热源热机的研制和优化设计提供新的理论指导.A model of a generalized irreversible Stirling heat engine is set up, the optimal performance of a Stirling heat engine with thermal resistance, heat leak and regenerative loss is studied. The optimal relation between the power and efficiency under heat leak by general heat transfer law is derived. The conclusions obtained here may provide the observed performance of a real heat engine and some new theoretical guidance for the manufacture and the optimal design of two-heat-source engines.
