摘　　要：根据热力学第一定律和均匀物质普遍适用的热力学性质,分别以温度和体积、温度和压强为独立变量,讨论以均匀物质为工作物质的准静态卡诺循环的效率,证明其效率均为η=1-T2/T1,从更普遍的角度证明了卡诺定理的正确性。On the basis of the first law of thermodynamics and thermodynamic properties of homogeneous materials, the efficiency of Carnot cycle in quasi-steady process is calculated by using temperature-volume and temperature- pressure as the independent variables respectively, and the results are η=1-T2/T1, which, in more general terms, shows the correctness of Carnot principle.
