| 摘 要： | 尝试在小世界网络结构上引入简化Blume-Emery-Griffiths动力学模型,描述三态舆论演化动力学过程。数值模拟结果表明内部热噪声T对舆论演化过程有较大影响,在一定条件下发现舆论演化过程类似于Ising铁磁体,内部热噪声T存在临界值。结果在一定程度上反映了现实舆论的形成过程,同时也印证了该模型的合理性。

| Abstract: | We introduce the Blume-Emery-Griffiths model to describe the dynamics of opinion formation,and the three-state opinion formation question is studied in small-world Networks.The simulation results show that the interior thermo-noise T has greater influence on the system,and the system has a critical value Tc.The systens evolution precess is similar to Ising ferromagnet.To some extent,the results reflect the opinion formation process,and also prove this model is reasonable. |
