许多现实世界的网络都具有模块化结构的特征。本文研究了小世界网络中传染病易感性-感染-不应-易感（SIRS）模型的模块效应对疾病传播的影响。仿真结果表明，模块结构与模块间连接的无序性和系统的平均度一起，会影响传播过程中的同步行为。更重要的是，我们发现平均度和模结构之间的相互作用可能导致系统的同步行为的非单调变化。
Many real-world networks are characterized by modular structure. In this letter, modular effects on epidemic spreading of susceptible-infected-refractory-susceptible (SIRS) model in small-world networks are investigated. Simulation results show that, together with the disorder of the inter-module connections and mean degree of the system the modular structure may affect the synchronization behavior in propagation. More importantly, it is found that the interplay between mean degree and modular structure may lead to a nonmonotone variation of the synchronization behavior in the system.
