Understanding the emotional contagion process in the crowd will help to take measures in advance to avoid the large-scale spread of negative emotions in emergencies and reduce the loss of lives and properties. Studying the phase transition phenomenon is fundamental to analyzing and evaluating the crowd emotional contagion. However, it is a challenging issue since most people participate in both the physical and cyber networks at the same time. In this article, we focus on the emotional contagion in physical-cyber integrated networks from the phase transition perspective. To achieve this, we first construct a physical-cyber integrated network model to describe the interactions between physical and cyber networks. Second, we build an emotional contagion model to capture the characteristics of emotional contagion in the physical and cyber integrated networks accurately. Finally, we study the phase transition phenomenon of emotional contagion and identify the critical threshold by mapping the emotional contagion to the joint site/bond percolation model. Numerical simulations and experiments further support and enrich our conclusions. The proposed method is expected to provide guidance for controlling emotional contagion in emergencies.
了解人群中的情绪传染过程将有助于提前采取措施，避免在紧急情况下负面情绪的大规模传播，并减少生命和财产损失。研究相变现象是分析和评估人群情绪传染的基础。然而，这是一个具有挑战性的问题，因为大多数人同时参与物理网络和网络网络。在本文中，我们从相变的角度关注物理-网络集成网络中的情绪传染。为了实现这一点，我们首先构建一个物理-网络集成网络模型来描述物理网络和网络网络之间的相互作用。其次，我们建立一个情绪传染模型来准确捕捉物理-网络集成网络中情绪传染的特征。最后，我们通过将情绪传染映射到联合位点/键渗流模型来研究情绪传染的相变现象，并确定临界阈值。数值模拟和实验进一步支持并丰富了我们的结论。所提出的方法有望为控制紧急情况下的情绪传染提供指导。
