摘　　要：以推广的Redlich-Kwong状态方程表示的实际气体为工质研究斯特林热机循环的输出功和效率.它涵盖了以理想气体、VDW气体、Dieterici气体、RK气体及低温气体为工质的斯特林循环的热力学性质.通过数值计算详细分析了循环输出功和效率分别与体积和温度之间的关系.所得结论不仅能导出相关文献的主要结果,而且可为热机的运行条件和优化设计提供理论参考.A generalized Redlieh-Kwong gas Stirling heat engine is established and the general expressions for its work output and efficiency are derived, from which thermodynamic prope VDW gas, Dieterici gas, RK gas and cryogenic gas Stirling cycles can be directly der sis is made of the relationships of the work output and efficiency of the Stirling heat and temperature. The results obtained here may be used to derive not only some im rties of the ideal gas, ived.
