In the engine model the only irreversibility of finite rate heat transfer is considered. The optimal relation between the power output and efficiency of the heat engine is also derived by using an equivalent temperature of the hot reservoir. The obtained results include those obtained in recent literature and can provide some theoretical guidance for the designs of practical engines. 关键词：FINITE time THERMODYNAMICS FINITE HEAT capacity RESERVOIR HEAT engine CYCLE OPTIMAL configuration OPTIMAL performance HEAT transfer law
