# 一类具有水平和垂直传播的连续SIR传染病模型的分岔性质Bifurcation Property of a Class Continuous SIR Model with Vertical and Horizontal Transmission

Abstract: Bifurcation property of a class SIR model with horizontal and vertical transmission is investigated. Firstly, the type of equilibrium points is determined by discussing its coefficient parameters. Then the transcritical bifurcation and normal form of the model is explored by center manifold theorem. Finally, biological mean of the model is also given.
