延迟微分方程的数值Hopf分支分析文的主要工作就是研究一类具时滞的Van der Pol方程的Hopf分支的性质。证明了该方程精确解和数值解Hopf分支的存在性，并分析了两种情况下的Hopf分支的分支方向及周期解的稳定性。

-THE NUMERICAL ANALYSIS OF HOPF

BIFURCATION FOR DELAY DIFFERENTIAL EQUATION

In this paper,a class of Van der Pol equation with delay is considered.The

property of the analytical and numerical Hopf bifurcation of the system is

investigated,including the direction of Hopf bifurcation and the stability of

periodic solution.
