摘　　要：采用大多数热力学教材中计算卡诺循环的效率的相同步骤,推导以状态方程为任意函数形式的气体为工作物质的卡诺循环效率,可作为教学内容的补充材料,以帮助学生深化对热力学定律的理解和麦克斯韦热力学关系式的应用.In most textbooks of thermodynamics,the Carnot efficiency is derived with the ideal gas as its working substance,which is done by calculating the heats involved in two isothermal processes and using the associated adiabatic relation for the ideal gas.In this paper,with the same procedure,the Carnot efficiency is calculated regardless of the functional form of the gas equation of state.It can be used as a supplementary teaching material for undergraduate students.
