摘　　要：从电磁理论角度出发,指出地磁对彩色显像管产品着屏位置的影响,对引起色纯不良的情况做了初步的分析。针对地磁的影响情况,介绍了实际采用的纠正彩色显像管着屏偏差的具体方法和途径。为确保彩色显像管产品色纯良好,介绍了模拟磁场的设立和使用要求。From the magnetic theory,the article points out that it is made primary analysis that landing screen effect of colour display from earth magnet will cause poor colour purity. To the earth magnet, it actually introduces to adopt the particular way and procedure of correcting drift of landing screen.For the sake of good colour purity of colour screen, the paper introduces setting of analog magnetic field and requirements of operation.
