摘 要: 采用Ляпунов函数方法,证明病毒感染的时滞免疫反应动力学模型dT/dt=γ-dT(t)-kT(t)V(t)dI/dt=kT(t)V(t)-δI(t)dV/dt=pI(t)-cV(t)的正平衡解稳定性,给出时滞的估计,证明时滞免疫反应系统的正平衡解渐近稳定和全时滞稳定条件. This paper studies stability of a class of time-delay immune response system {dT/dt=γ-dT(t)-kT(t)V(t);dI/dt=kT(t)V(t)-δI(t);dV/dt=pI(t)-cV(t)} By using the qualitative theory of differential equation and constructing Ляпунов functions,the bounded of time-delay and sufficient condition that guarantees positive equilibrium of system asymptotic stable are obtained.
