主要研究了带有非线性发生率(βISq )和两个平行传染阶段的时滞脉冲传染病模型。利用比较原理,证明当 R1<1,R2<1时无病周期解的全局吸性,并给出当 R3>1,R4>1时疾病持续生存的充分条件。

We mainly study the impulsive delayed epidemic models with nonlinear incidence (βISq ) and two parallel infectious stages .According to the methods of nonlinear analysis by using the comparison principle ,the global attractivity of infection-free periodic solusive was verified when R1 <1 and R2 <1 ,and a sufficient condition for the permanence of the epidemic was also given when R3 >1and R4 >1.
