备注

提出了一种具有无标度、增长性和优先连接特性的网络模型,并且分析了网络模型的构造算法,刻画了网络结构的点、边数目特性,计算了网络模型的度累积分布,论证了外边数可变的阿波罗网络的度累积分布均满足幂律分布.进一步研究了瓦解度等指标,对该网络结构受到蓄意攻击后的受损程度进行了评价.

A network model that features scale-free characteristics,growth and priority connectivity is proposed.Furthermore,the construction algorithm of network model is elaborated.Using mathematical tools,we describe the number of points and edges of network structure.The degree accumulate distribution of network model is calculated, and the Apollo network is generalized by mathematical methods.As a result,we have proved that all Apollo networksstructure with variable outer numbersatisfy the power-law distribution.Finally,the degree of disintegration and other indicators are studied,and the damage degree of the network structure after intentional attack is evaluated.
