Self-Organized Criticality Analysis of Earthquake Model Based on Heterogeneous Networks

原来的 OlamiFederChristensen (OFC ) 模型，显示柔韧的幂定律行为，是 quasistatic 地震的 BurridgeKnopoff 春天块模型的二维的版本。在这份报纸，我们基于异构的网络介绍一个修改 OFC 模型，改进原来的模型的再分配规则。它能被看作原来的 OFC 模型的归纳。我们数字地调查参数的影响并且，它分别地在我们的网络控制拓扑的生长和内部选择动力学的发展机制的紧张，并且发现在参数空格有二个不同阶段(，) 。同时，我们学习控制参数的影响任何一个。增加一，模型的地震行为从本地人转到全球。

The original Olami-Feder-Christensen （OFC） model, which displays a robust power-law behavior, is a quasistatic two-dimensional version of the Burridge-Knopoff spring-block model of earthquakes. In this paper, we introduce a modified OFC model based on heterogeneous network, improving the redistribution rule of the original model. It can be seen as a generalization of the originM OFC model We numerically investigate the influence of the parameters θandβ, which respectively control the intensity of the evolutive mechanism of the topological growth and the inner selection dynamics in our networks, and find that there are two distinct phases in the parameter space （θ,β）. Meanwhile, we study the influence of the control parameter a either. Increasing a, the earthquake behavior of the model transfers from local to global.
