脉管在脉管制冷机中所起的作用,主要体现在热力学和动力学两方面。由热力学平衡计算可决定脉管制冷机的尺寸,但同时也要进行动力学上的匹配。着重利用Dr.deBoer的热力学分析方法对脉管内的气柱位移进行了定量计算 ,给出了计算结果 ,并进行了讨论 The role of vessels in pulse tube chillers is mainly reflected in both thermodynamics and kinetics. The calculation of the thermodynamic equilibrium determines the size of the cryogenic refrigerator, but at the same time it also requires a kinetic match. Emphasis on the use of Dr. de Boer thermodynamic analysis of vascular internal column displacement was given a quantitative calculation given the results and discussed
