摘　　要：本文采用磁标位的傅里叶展开法对偏转线圈中的磁场进行分析,并提出了一种具体的设计方法,将结构参量和偏转磁场的分布紧密联系起来.最后对如何调整偏转线圈的分布以校正光栅畸变,进行了一些定量分析.The Magnetic scalar potential is mostly used to describe the deflection field instide the picture tube. In this paper, basing on the magnetic scalar potential's Fourier har monic anlysis, we derive the analytical formulas for the magnetic deflection coils. And then, a kind of deflection coils is desiged. Using the formalas, we can knon How to correct the distortion raster._______________________________________
