摘要
3He作为一种特殊的工质在低温工程、空间技术和基础物理学研究等领域逐步得到应用 ,尤其是它在 2 6mK以下才具有的超流性使它能够起到其它任何流体都无法获得的特殊作用 ,比如获取mK级超低温环境。该文介绍了3He超流性的发现、特征以及研究进展 ,从量子力学角度阐述了3He与4He超流性的联系和区别 。
The special substance ~3He is now having more and more applications in the fields of the cryogenic engineering, space technology and fundamental physics research, etc. Its superfluidity below 2 6 mK enables ~3He to play a unique role in these applications against any other working fluid. The discovery, the characteristics and the research developments of the ~3He superfluidity are introduced in this paper. The relations and differences of the superfluidity between ~3He and ~4He are explained by quantum mechanicals. Applications of superfluid ~3He are introduced.
