摘　　要：低温超导技术在基础科学研究中的广泛应用,极大的带动了低温工程的技术发展。通过介绍超流氦在大型低温系统中的应用优势,国内外几个典型超流氦低温冷却系统的流程、性能指标以及运行情况。分析了大型超流氦低温冷却系统的主要设备构成、热力循环方案以及关键设备、关键技术突破方向。While the applications of low temperature superconducting technology in basic scientific research spread widely,the development of cryogenic engineering was greatly accelerated,and lots of large helium cryogenic systems were established successively. The processes,performances and operating conditions of several typical superfluid helium cryogenic systems were described in detail. The advantages of the application of the super flow helium in the large-scale cryogenic system are introduced and the main equipment composition,the thermodynamic cycle scheme and the key equipment,the key technology breakthrough direction are analyzed in this paper.
