考虑总人口是非常数的SIRS传染病模型,在不考虑空间扩散和考虑空间扩散两种情形时,分别构建了Liapunov函数并讨论了其模型的常数平衡点的稳定性.
Dynamic models of infectious diseases with changeable total population are investigated. In two cases which considering the spatial diffusion and not considering the spatial diffusion, we respectively constructed Li- apunov functions and discussed the stability of the constant equilibriums to the models.
