摘要
研究了具有指数出生,标准发生率的脉冲预防接种的SIQR模型.讨论了其无病周期解的存在性,给出了无病周期解的全局稳定性分析.并利用数值仿真对结论进行了验证,最后获得了系统一致持续生存的条件.
In this paper,the SIQR model with prevention and vaccination and standard incidence ratio is studiel.The existence of infection-free periodic solution is analyzed,and the stability in the large of infection-free periodic solution is concluded.By analyzing the figures simulation and verifing the results,the exact conditions with systematic consistency and sustainable survival are obtained.
