Network Public Opinion Propagation Control Model of Major Emergencies Based on Heat Conduction Theory

In physics, the process of heat conduction of objects is similar to the process of network public opinion propagation of major emergencies. Based on the theory of heat transfer, this paper analogizes the process of network public opinion information propagation and object heat conduction and analogizes the exchange of network public opinion information between individuals in social networks to the course of object heat transfer. Based on the accumulation of individual energy in social network, the propagation model of network public opinion is established, and the propagation control model of network public opinion in major emergencies is established based on the heat conduction theory. The influence of individual interest, propensity to spread, transmission coefficient of network public opinion information, and the breadth of dissemination on the dissemination of network public opinion in major emergencies are analyzed, respectively. This study provides some inspiration for the disposal and governance of network public opinion, propagation of major emergencies.
