离子光学系统求解象差系数四阶的S—G关系

The Solition to Grade-4S-G Relation Aberration Colfficient in Particle Opricl System

本文是文献［１］的后续部分．本文将进一步给出求解Ｇ—Ｓ关系的计算机实现过程和手工反解得到的四阶Ｓ—Ｇ规则，从而为计算四阶离子轨迹及其斜率奠定基础．

The thens is a contiruled part of donment[1]. The Solution to G-S relation by computer and grade-4 S-G princikle obtained with manual reverse solution are precented so as to prpcide a foundation for the calculation of grade -4 particle locue and its slope.
