振动线准直技术是一种通过直接测量空间磁场分布情况来进行磁铁设备准直的方法，其原理完全不同于目前国内正在使用的基于磁铁机械结构进行准直的方法。振动线方法具有很高的准直精度和灵敏性，可以用于单个磁铁磁中心测量、磁铁准直标定和多块磁铁磁中心准直等。主要介绍了振动线准直技术的原理、起源和国际上的应用研究概况。

The vibrating wire technique is used as an alignment method which carries out magnets alignment by measuring the magnetic field of the magnets. It is different from the alignment method based on the mechanical structure of the components. The vibrating wire technique demonstrates high measurement precision and high sensitivity. It can be used in many ways, such as for measuring the magnetic center of a single magnet, for magnet fiducialization, and for magnetic center alignment of several magnets. This article mainly introduces the principle, theoretical conclusions and the research overview of the vibrating wire technique.
