摘要：
A novel epidemic SIRS model with distributed delay on complex network is discussed in this paper. The formula of the basis reproductive number R-0 for the model is given, and it is proved that the disease dies out when R-0 < 1 and the disease is uniformly persistent when.. 0 > 1. In addition, a unique endemic equilibrium for the SIRS model exists when R-0 > 1, and a set of sufficient conditions on the global attractiveness of the endemic equilibrium for the system is given.
