介绍了在相同脉管制冷机结构参数的条件下．分别配以有阀及无阀压缩机的实验结果。实验表明，通过仔细的时序调节有阀型脉管制冷机可获得更好的制冷性能。 The condition of the same vascular refrigerator structural parameters is introduced. Respectively with the valve and valveless compressor experimental results. Experiments have shown that better chilling performance can be achieved through careful timing adjustment of valved pulse tube chillers.
