摘　　要：本文利用修正的理想气体状态方程推导出以理想费米气体He为工作物质的量子斯特林制冷循环的制冷系数和输入功的一般表达式,讨论在高温和低温两种极限条件下循环的制冷系数,分析了量子简并对循环制冷系数的影响。所得结论可为低温气体制冷机的研究提供理论依据。The general expressions for the coefficient of performance and work input of the Stirling refrigeration cycle working substance with ideal Fermi gas 3He are determined by using the corrected equation of state.The coefficient of performance is derived in the high-low temperature .The effect on the coefficient of performance is analysed.These results will be significant for the research of gas refrigerators in the low temperature.
