一类具有常数移民的SIR和SIS组合流行病模型
A Class of The Combination of SIR and SIS Epidemic Modelwith Immigrants of Constant
【摘要】 建立了一类具有常数移民的SIR和SIS组合流行病模型,利用微分方程稳定性理论和方法讨论了该模型平衡点的稳定性,并且给出了疾病是否流行的基本再生数.
【Abstract】 A class of the combination of SIR and SIS epidemic model with immigrants of constant is studied. The stability of differential system equilibrium is discussed by means of the stable theory and method of differential equation. And the basic reproduction parameter for the possibilly of malaria pandemic is given.
