Abstract: In this article Various kinds of methods about the solution of nonlinear system dx/dt＝F(x, λ) after the Hopf Bifurcation are discussed. We improve the method metioned in reference [2] and give the numerical solution of the van der Pol equations.

Key words: Hopf bifurcation, continuation methods, limit circle

摘要： 讨论了求解非线性系统dx/dt＝F(x, λ)Hopf分叉后周期解的各种方法，改进了文献[2]中提出的方法，并给出了vanderPol方程的数值解。
