摘　　要：为了研究病毒传播过程中个体的运动行为对网络结构的影响,提出了一种个体具有躲避行为的病毒传播模型,通过三种情况下的对比研究发现,个体的躲避行为能够使网络的结构从随机网络转换为一种宽标度网络,并且发现系统在演化过程中个体的躲避行为能够使网络的度—度相关性发生变化,这证实了个体的躲避行为确实对会网络结构产生影响。In order to study the influence of the individuals’escaping behavior on the structure of network during the virus spreading process,this paper proposed a new virus spreading model. In the model,included the escaping behavior of individuals. Studied the evolving process of the system under three different cases. The result shows that the individuals’escaping behavior can lead the network changes from random network to broad scale network. At the same time,the degree-degree relativity of the network was changed during the evolving process. These results prove that individuals’escaping behavior can really cause the change of network’s structure.
