摘　　要：在计算了惰性气体二元混合工质的热力学参数之后,采用氦-氩混合气体作为工质来提高热声驱动脉管制冷的性能。实验结果表明,热声驱动脉管制冷机采用适当配比的氦 氩工质可获得比纯氦更加优越的制冷性能。Based on the computation of thermodynamic properties of binary inert gas fluids, He-Ar mixtures were used as working fluids to improve the refrigeration performance of a thermo acoustically driven pulse tube refrigerator. The experimental results indicated that the refrigeration performance with appropriate He-Ar mixtures was better than that of pure He.
