摘　　要：对不同张角的一组偏转线圈的Ｈ_z分量对偏转像差的影响进行了计算分析。结果表明，在应用偏转磁场的解析式进行偏转像差分析时，偏转磁场的Ｈ_z分量是必须考虑的，这个分量对偏转像差和Ｔｒｉｌｅｍｍａ常数、偏转像差的校正和优化场分布产生十分大的影响。Influence of the Hz component of the deflection magnetic field, produced by a group of deflection coils with different field angles on deflection aberration, was theoretically analyzed. The results show that the Hz component strongly affects both deflection aberration and Trilemma constant and that it plays a significant role in deflection aberration correction and field distribution optimization.
