摘要
回顾了最近几年脉管制冷机取得的成就。由于它在低温下没有运动部件，较其它类型的制冷机具有振动小、可靠性高、寿命长、造价低等优越性。是极具潜力的一种未来空间用制冷机。
The author reviews the history of the improvements of the pulse tube refrigeratos. The pulse tube refrigerator contains no moving parts at its cold head and has considerable system advantages over most other types of cryogenic refrigerators in terms of reliability ,lifetime,vibration and cost.We can see its promising application in space science and technol。gy.
