摘　　要：斯特林热机是一种外部加热的闭式循环的热气机,具有效率高、热量来源广、噪声低等优点。斯特林热机根据基本构型不同,可分为α型、β型、γ型三种类型。针对γ型斯特林热气机建立等温模型及加热器、冷却器计算模型,分析了加热器无益容积比、冷却器无益容积比等参数对系统的输出功率、相对卡诺循环效率等的影响关系。The stirling engine is a closed cycle by external heat,it has many advantages,such as high efficiency,wide heat source and low noise.The stirling engine can be divided into three types by different structure,α-type,β-type,γ-tpye.The mathematic model of theγ-tpye stirling engine is built and we analysis the parameters,such as the unhelpful volume ratio of heater,the unhelpful volume ratio of cooler,influencing output power,relative Carnot cycle efficiency.
