摘　　要：网络病毒的爆发给计算机用户带来巨大的损失,同时互联网被认为是无标度网络,因此研究病毒在无标度网络上的传播及控制很有意义。通过构建一个BA无标度网络模型,对病毒的传播行为及影响因素进行了仿真分析。研究表明,采取恰当的策略可以有效地控制、预防病毒传播。Network virus outbreak brought huge losses to computer users. It was found that Internet had the features of scalefree. So the research on simulation of virus propagation and control in scale-free networks was significant. Through building a BA scale-free network, studied the simulation of the propagation of virus and influencing factors. The fruitful simulation results show that appropriate policies can effectively control and prevent the propagation of virus.
