谣言传播是一种典型的安全威胁现象。因此，有必要研究复杂网络中谣言传播的演化机制。考虑到谣言传播过程中的犹豫状态，在已有的谣言传播模型基础上增加了骑墙派，提出了一种新的SIFR谣言传播模型。推导了描述复杂网络中谣言传播动力学的平均场方程。为了确定有效的谣言控制策略，本文进一步分析了网络结构，提出了一种基于拓扑势理论的中心节点搜索和网络划分算法。
Rumor spreading is a typical phenomenon which poses security threats. Therefore, it is necessary to study the evolution mechanism of rumor spreading in complex networks. Considering the hesitating state in rumor spreading, we supplement fence-sitter group on existing rumor spreading models, then propose a novel SIFR rumor spreading model. The mean-field equations are derived to describe the dynamics of the rumor spreading in complex networks. In order to identify effective rumor control strategies, we further analyze the networks structure and propose an algorithm based on the topology potential theory to search the center nodes and divide the network.
