摘要：
In this paper, a class of SIRS epidemic model with time delay is considered. By applying the frequency domain approach and analyzing the associated characteristic equation, the existence of bifurcation parameter point is determined. If the coefficient tau is chosen as a bifurcation parameter, it is found that Hopf bifurcation occurs when the parameter tau passes through a critical value. Some numerical simulations for justifying the theoretical analysis are also provided.
