摘要
建立了一类具有垂直传染和多类易感者的流行病脉冲微分系统,证明了系统无病周期解的存在性和全局吸引性,并进一步给出了系统持续生存的条件.
According to the propagation of the epidemic, an epidemic system with vertical transmission and differential susceptibility were established. The existence and global attractivity of the infection-free periodic solution of this system were proved. Especially, the sufficient conditions were given to ensure the persistence of the system.
