摘要 主要研究托卡马克装置三次系统的Lyapunov量计算问题,给出一般平面多项式系统到其基本复形式之间的转换及其转换公式;利用Lyapunov量复算法在Maple计算程序下,计算出该三次一般系统的Lyapunov量,得到原点是其一阶细焦点的结论. The computation of Lyapunov values for Tokamak cubic system is mainly investigated in this paper. Transformation relationship and transformation formulas between general planar polynomial systems and their standard form are given. Under Maple computational program, the Lyapunov values for this cubic system are computed by using the complex algorithm of Lyapunov values. It is also presented that the highest order of fine focus is 1.
