摘要: 研究了一个具滞后免疫增殖的病毒模型.若病毒基本再生数小于1,无病平衡点全局渐近稳定,否则时滞将导致Hopf分支和混沌等复杂动力学性态的出现.Abstract: Aviralinfectionmodelwithdelayedimmuneresponseisstudied.Ifthebasicreproductiverateofthevirusislessthanunity,theinfection-freeequilibriumisgloballyasymptoticallystable.Otherwise,thetimedelayistocreatearichdynamics,suchasHopfbifurcationsandchaos.
