研究了一类两种群相互竞争的具有脉冲出生率的SIS传染病模型.通过理论分析,给出了各类周期解渐近稳定性的条件,并与相应的不具有脉冲出生率的SIS传染病模型进行了比较,揭示了两者的区别和联系.
A SIS epidemic model of two competitive species with birth pulses is studied. By theoretical analysis, the asymptotic stabilities of the periodic solutions are gived. The models with birth pulses and without birth pulses are compared, and the sameness and difference between the two models are revealed.
