摘　　要：[目的/意义]厘清时空隔断对信息扩散的影响,对减少信息冗余、建立良好的社会关系具有一定意义。[方法/过程]考虑线下时空隔断对信息扩散的影响,基于传染病模型,分别使用线下均匀网络、随机游走网络与线上网络进行耦合构建双层信息扩散网络模型,并通过数值仿真对这两类双层网络上的信息扩散行为进行分析。[结果/结论]相较于单层网络,双层网络中信息扩散的范围更广、速度更快且持续时间更短;依次增加隔断时间,信息扩散的范围和速度会逐渐减小且持续时间会相应延长;在时空隔断为6时,双层网络信息扩散的效率与范围都会低于单层网络。[Purpose/significance]Clarifying the influence of spatiotemporal partition on information diffusion is of some significance in reducing information redundancy and establishing good social relations.[Method/process]Considering the influence of offline spatiotemporal separation on information diffusion,based on the infectious disease model,this paper used office offline uniform network,random walk network and online network to couple to construct a two-layer information diffusion network model,and analyzed the information diffusion behavior on these two types of two-layer networks through numerical simulation.[Result/conclusion]Compared with the single-layer network,the information diffusion in the two-layer network is wider in scope,faster in speed and shorter in duration;when the partition time is increased sequentially,the scope and speed of the information diffusion will gradually decrease and the duration will be prolonged accordingly;when the spatial and temporal partitions are 6,the information diffusion of the two-layer network is less efficient and less extensive than that of the single-layer network.
