摘　　要：微信小程序解决了一些冗杂却必要的低频使用的应用程序放置,提供更为精准的服务,提高信息传播效率。文章基于传统SIR模型,加入用户黏度因素,提出改进模型并且研究易感节点、传染节点以及免疫节点的变化情况。MATLAB仿真结果表明,用户黏度越大,信息获取和传播速率越大,改进的SIR模型能较好地解释相关因素对微信小程序中信息传播的影响。WeChat applet solves some redundant but necessary low-frequency application placement,providing more precise services and improving information transmission efficiency.Based on the traditional SIR model and adding user viscosity factors,this paper proposes an improved model and studies the change of susceptible nodes,infectious nodes and immune nodes.The MATLAB simulation results show that the greater the user viscosity and the greater the information acquisition and propagation rate,the improved SIR model can better explain the influence of the related factors on the information transmission in the WeChat small program.
