中文摘要: |
提出了一个数学模型,用于研究脉冲投放免疫因子对HBV传染病动力学的影响.
通过利用脉冲微分不等式和比较定理,证明了HBV 模型的无病周期解的存在性, 给出了无病周期解的全局渐近稳定性和系统的持续性的充分条件.
研究结果表明: 短的投放周期或适当的免疫因子投放量可以导致HBV 的清除. |
英文摘要: |
A mathematical model is proposed to study the transmission dynamics of hepatitis B virus (HBV) treated with impulsive releasing immune factor.
Using the impulsive differential inequality and comparative theorem, the authors investigate the existence of infection-free periodic solution of the impulsive HBV system, the sufficient conditions for the global asymptotic stability of the infection-free periodic solution and for the permanence of HBV. Analysis results indicate that a short releasing period of the immune factor or a proper pulse releasing quantity leads to the eradication of the HBV. |
