摘　　要：研究了蓄意攻击和随机攻击对BA网络、CAG网络、PA网络的拓扑性质(度分布,点强度分布,聚类系数和匹配系数等)的影响,结果表明:网络拓扑性质对随机攻击具有鲁棒性,而对蓄意攻击具有脆弱性.Several important complex network models are presented in detail in this paper,such as scale free network,common accelerating growth network and poverty alleviation network. We aim to study the effects of different attacks on the topology structure. Degree distribution,strength distribution,clustering coefficient,assortativity coefficient have been carefully discussed in the paper. Moreover,we reach the conclusion that the topology structure is robust against random failure and frangible to intentional attack.
