摘要: 应用GainesMawhin迭合度理论, 证明在脉冲预防接种策略作用下受季节驱动的SIRS模型周期解的存在性, 并通过数值模拟对比不同丧失免疫力率对传染病模型的影响.

关键词: SIRS模型, 脉冲接种, 周期解

Abstract: Using the coincidence degree theory of GainesMawhin, we proved the existence of periodic solutions for seasonally forced SIRS models with pulse vaccination. The effects of different loss of immunity rates on the infectious disease models were compared by some numerical simulation.

Key words: SIRS model, pulse vaccination, periodic solution
