摘要
本文首次将霍尔效应与锁相技术结合起来，制成高精度稳恒磁场测试仪，并采用回归分析法，成功地用于监视器偏转线圈，特别是各种永磁校正元件的磁场分布的测量及分析，能对优化偏转线圈的结构，永磁校正元件的设计工作提供实际的指导。
This paper first describes the combination of Hall effect and lock-in amplifier technology, on the basis of which , a high precision magnetic field measurement instrument has been developed to do the measurement and analysis for the cathode ray tube (CRT) deflection yoke magnetic field ,especially for the magnetic field by the correction permanent magnets. The instrument is very useful for the optimum design of CRT deflection yoke without correction permanent magnetic parts.
