由于缺乏纵向数据，网络动力学的实证研究一直受到限制。在这里，我们引入了一个定量指标的链接持久性探讨之间的相关性的移动的电话网络的结构和持久性的链接。我们发现，持久的链接往往是互惠的，更常见的人与低程度和高集群。我们研究了冗余的持久性，程度，集群和互惠性之间的关联，互惠性是最强的预测领带持久性。所提出的方法可以很容易地适应于其他网络的动态特性，并可用于确定最有可能在未来生存的链接。(c)2008 Elsevier B.V.保留所有权利。
The empirical study of network dynamics has been limited by the lack of longitudinal data. Here we introduce a quantitative indicator of link persistence to explore the correlations between the structure of a mobile phone network and the persistence of its links. We show that persistent links tend to be reciprocal and are more common for people with low degree and high clustering. We study the redundancy of the associations between persistence, degree, clustering and reciprocity and show that reciprocity is the strongest predictor of tie persistence. The method presented can be easily adapted to characterize the dynamics of other networks and can be used to identify the links that are most likely to survive in the future. (c) 2008 Elsevier B.V.
