在加速器粒子动力学系统和带电粒子光学系统中,高阶象差系数的推导是一项十分冗长而繁杂的工作,靠人工推导很容易出错,有时十分困难。国外在用计算机代数简化象差推导工作中作了不少努力。由于传统的研究象差的方法难以得到任意阶象差方程的
In accelerator particle dynamics and charged particle optics, the derivation of higher-order aberration coefficients is a very lengthy and complex task that can be very error-prone and difficult at times. Abroad in the use of computer algebra simplified aberration deduction made a lot of efforts. Due to the traditional methods of studying aberrations, it is difficult to obtain any order aberration equation
