】首次采用氢氦二元混合工质在脉管制冷机中进行了实验研究。试验结果表明：在其它运行参数不变的情况下，采用氦氢二元混合工质可以提高脉管制冷机在８０Ｋ温区的制冷量，当氢的摩尔浓度为２０％时，其制冷量比纯质氦提高了约１０％。
】 For the first time using hydrogen and helium mixed refrigerant in a pulse tube cooler in an experimental study. The experimental results show that the refrigeration capacity of the pulse tube refrigerator at 80K can be increased by using the hydrogen-hydrogen mixed refrigerant when the other operating parameters are unchanged. When the hydrogen molar concentration is 20%, the refrigeration capacity ratio Pure helium increased by about 10%.
