  • 讨论了一类具高阶奇点的高次非线性系统,得到了计算焦点量的递推方程,其中的待求量满足线性方程,且线性地依赖已求得的各量,从而降低了计算难度和计算量.作为一个简单应用,讨论了一类五次多项式系统的中心与焦点判别问题并举例仿真.

     

    A class of higher power nonlinear systems with higher order singular point are discussed in the paper. A series recursive equations for the calculation of focus value are obtained. An application on power-5 system are given and the concrete simulation verifies the theory.
