摘　　要：提出了采用合适的混合工质代替纯质氦以提高脉管制冷机在８０Ｋ温区制冷量的新构思。概述了国外在制冷循环、天然气液化及Ｊ－Ｔ节流制冷中应用混合制冷剂从而提高系统热力学效率的研究成果，及国内对混合物低温制冷性质的研究进展情况，进一步论证了混合工质应用于脉管制冷机的可行性。The authors give a novel conception that in order to increase the cooling capacity of a pulse tube refrigerator at 80K temperature range, refrigerant mixtures are introduced instead of pure helium. The essay provides a brief review on application of refrigerant mixtures in refrigeration cycle, nature gas liquifaction and J-T throttle refrigerator etc., based on which it expounds the possibility of refrigerant mixtures applying in a pulse tube refrigerator.
