摘　　要：提出了利用内复叠节流制冷循环获得３０ Ｋ～６０ Ｋ温区的新制冷方案。进行了与之相关的热力学问题分析，建立实验装置，首次获得了５０A new thermodynamic process for obtaining the temperature range from 30K to 60K was proposed based on the auto cascade mixed refrigerant refrigeration(AMR)cycle.An experimental set up was made to verify the proposed thermodynamic cycle.In the experiment a no load temperature of around 50K was achieved successfully.
