摘要
考虑了具有饱和接触率和变化种群大小的脉冲时滞的SVEIR模型,使用比较原理得到了模型的持久性,即R>1时,系统是持久的,并通过数值模拟验证了获得的结果.
A pulse vaccination delayed SVEIR model with saturation incidence and a varying total population is proposed in this paper.By applying the comparison theorem,the permanence of pulse delayed SVEIR model is obtained when R > 1.Finally,numerical simulations are carried out to explain the results.
