摘要
介绍了几种用于空间制冷中的氦制冷技术，如３Ｈｅ减压蒸发制冷、３Ｈｅ压缩相变制冷、亚临界液氦制冷、超流氦制冷等。分别介绍了它们的原理，关键技术及其应用实例，最后提出了开展这方面工作的建议。
In this paper some kinds of Helium Refrigeration applications in space refrigeration technology are introduced,such as refrigeration technology of 3He evaporation by decompression,refrigeration technology of 3He phrase transformation by compression,refrigeration technology with subcritical liquid helium and refrigeration technology with superfluid helium.We discuss separately their basic principle,key technology and examples.At last,some ideas about how to work in this field are given.
