| 摘 要： | 本文讨论了离子光学系统中离子轨迹方程的特点和逐次逼近求解法。利用人工智能语言的符号运算功能,提出了计算机推导象差系数的新方法。并举非均匀磁场(主场)轴向三阶象差系数为例,以示此方法的实用意义。

| Abstract: | The characteristic and successive approximation solution of the ion trajectory equation in ion opti-
cal System are discussed.Using the symbolic operation of the artificial intelligent language,a new
method is developed to yield aberration coefficients with the aid of a computer. AS examples,axial
aberrations of third order for inhomogeneous magnetic field(main field)are given to show the practical
application of the method. |
