摘要
研究了一类具有脉冲预防接种的SEIRS传染病模型,利用对模型等价系统的分析,得到了模型无病周期解具有全局吸引性的存在条件,并且给出了疾病的持久性的存在条件.
In this paper, a disease transmission model of SEIRS type with pulse vaccination strategy is studied. We obtain the existence conditions with the global attractive of infectionfree periodic solution by the analysis of the equivalent system of the model, and give the existence of the persistent of the disease.
