摘要
综合介绍国外，主要是美国、西欧空间低温技术的最新进展。论述超流氦冷却技术及空间飞行中的液氦再供给等在轨机载验证、低温风洞技术、氢浆的制备和应用前景等。重点讨论目前在空间探测过程中最具竞争性的斯特林制冷机和脉管制冷机的最新发展。对可望在空间中应用的毫开（ｍＫ）级３Ｈｅ—４Ｈｅ稀释制冷机和绝热退磁制冷机及其它制冷技术也作简要介绍。最后对发展我国空间低温技术提出了建议。
In this paper,the newly development of international space cryogenic techniques,especially in America and West European countries has been summerized.Including the superfluid helium,the providing of liquid helium to the plant in the space on orbit,cryogenic wind tunnels techniques,the preparation and application of slush hydrogen etc.The summery emphasized on the most competitive equipments Stirling cryocooler and pulse tube cryocooler.Fruther,the techniques of 3He- 4He dilution refrigerator and magnetic cooler have also been introduced in brief.Finally,the suggestion for the development of Chinese space cryogenics has been discussed.
