考虑了时滞方程的两类接种策略.连续接种的系统中,研究了无病平衡点的局部渐近稳定性和地方病平衡点的全局渐近稳定性;脉冲作用下的传染病模型,利用脉冲比较定理和微分不等式得到了无病周期解的全局吸引性的条件,最后对两类接种进行了比较并得出结论.

In this paper,two vaccination strategies about delayed equations were studied .In the model with continuous vaccina-tion,the local stability of a diseasr-free equilibrium and the global stability of a endemic equilibrium were studied .A pulse under the action of infectious disease model was considered ,using the comparison principle and pulse differential inequality , the global attractivity of infection -free period solution and the sufficient conditions for permanence of the disease were ob -tained.Finally,the two vaccination strategies were compared and relevant conclusions were obtained .
