| 摘 要： | 针对无标度网络模型，考虑新增节点可能与系统存在关联的特性，提出了基于关联度的一种改进模型，从理论上对新模型的度分布进行了分析；通过计算，将度分布、聚类系数和平均路径长度等网络参数与适应度模型进行了比较，计算结果表明，关联度模型比适应度模型更优。

| Abstract: | An improved evolution model of scale - free network based on correlation degrees between the new node and the system was proposed. The degree distribution of the new model was analyzed theoretically. The parameters of new network, such as degree distribution, clustering coefficients and average path length, were calculated to compare with that of fitness model. The results show that the correlation degree model is better than the fitness model. |
