中文摘要：

当永磁体在高温超导体附近时，部分磁力线进入超导体肉，由于磁通钉扎作用，永磁体无需控制而稳定悬浮，这种悬浮特性称为无源自稳定性。这种特性的重要应用之一就是高温超导轴承。由于具有无源自稳定性、无摩擦、低损耗等优点，高温超导轴承越来越受到国内外关注，成为研究的热点，已经应用在飞轮储能、高速旋转机械等重要领域。本文介绍了高温超导悬浮轴承的工作原理，比较了轴向型和径向型高温超导轴承的结构特点，详细地说明了国外研究进展和国内的发展现状，探讨了高温超导轴承当前的研究热点和应用领域。

英文摘要：

When the high-temperature superconductor obtains the superconducting state, part of the magnetic flux lines enter into the superconductor and the permanent magnet can levitate stably without control due to flux pinning effect. This levitation characteristic is passive self-stability. One of the important applications of this characteristic is the high-temperature superconducting bearings （HTSB）. Due to the advantages of passive self-stability, non- contact and low-loss, etc. it attracts more and more attention, and has some applications in flywheel energy storage system （FESS） , high-speed rotor and rotating machinery. This paper introduced main structure of HTSB and its basic working principle. The axial-type HTSB is compared with radial-type HTSB in configuration. And the development status of HTSB designing institutions at home and abroad in detail are presented. In the end, the focus on current research and its applications are also discussed.
