摘　　要：基于弱耗散假设,求出卡诺热机的输出功率和效率的表示式,进而导出输出功率与效率间的优化关系,由此讨论不可逆卡诺热机的一般性能特性,并简便地获得文献中的一些重要结果.Based on the weak dissipation assumption, the expressions for the power output and efficiency of a Carnot heat engine are obtained and the optimal relation between the power output and the efficiency is derived. The general performance characteristics of the irreversible Carnot heat engine are discussed. Some of the important results appearing in the literature are conveniently deduced.
