我们设计加工了一套测量摇摆磁铁整体场分布的测量装置，并对北京自由电子激光（ＢＦＥＬ）摇摆磁铁进行了实际测量，定态测量误差优于１×１０￣（－４），动态测量误差５×１０￣（－４）。
We designed and measured a set of measuring device for measuring the overall field distribution of rocking magnets. The BFEL rocking magnet of Beijing was measured. The measurement error of stationary state was better than 1 × 10 ~ (-4). The dynamic measurement error 5 × 10 ~ (-4).
