摘　　要：[目的/意义]互联网时代,人们拥有网民和现实社会人双重身份,可以同时在线上互联网社交网络和线下社会人际网络两种渠道传播话题,本文提出了一种模型来研究这种舆情传播现象。[方法/过程]采用Price网络和WS网络模拟线上线下网络层,通过一定的关系连接设计了传播的耦合网络载体。针对线上辐射传播,线下选择传播的特性以及节点双渠道传播的状态变化规律,构建了线上线下互动舆情传播模型SIR_2O。[结果/结论]实验结果表明,线上线下互动扩大了话题传播的速度和广度,下传率和上传率都与传播覆盖率呈正相关关系,其联合作用存在传播阈值。[ Purpose/Significance] In the Interact era, the people possess dual identition as both cyber citizen and real social person. So they can spread topics through dual channels of the online interact and the offline social network simultaneously. In this paper we propose a model to study this phenomenon of public opinion propagation. [ Method/Proceas ] Using the Price and WS network, we simulate the on- line and offline network, and design the bearer network in a certain way. For the radiation propagation online, the selective propagation of- fline, and the node status change through dual channels, build the SIR_20 model. [ Result/Conclusion] The simulation results show that the spread through dual channels of online and offline network expands the breadth and velocity of topic diffusion, the upload rate and download rate positively related to the transmission rate. There is a threshold of their joint action influencing the transmission rate.
