摘要
对具有两个时滞的综合国力模型,通过分析线性方程对应的超越特征方程根的分布情况,运用Nyquist准则,研究平衡点的稳定性和局部Hopf分支性质,得到平衡点稳定的充分条件及产生Hopf分支的条件,并给出了模型的解释.
In this paper we consider the comprehensive national power model with two aelays, l ne local stability of the equilibrium and the property of local Hopf bifurcation are discussed by analyzing the corresponding transcendental characteristic equation of the linearized equation and empolying Nyquist criteria. Then we explain some of the results.
