第742行： − − ==Spread of content in networks== − − Content in a [[complex network]] can spread via two major methods: conserved spread and non-conserved spread.<ref>Newman, M., Barabási, A.-L., Watts, D.J. [eds.] (2006) The Structure and Dynamics of Networks. Princeton, N.J.: Princeton University Press.</ref> In conserved spread, the total amount of content that enters a complex network remains constant as it passes through. The model of conserved spread can best be represented by a pitcher containing a fixed amount of water being poured into a series of funnels connected by tubes. Here, the pitcher represents the original source and the water is the content being spread. The funnels and connecting tubing represent the nodes and the connections between nodes, respectively. As the water passes from one funnel into another, the water disappears instantly from the funnel that was previously exposed to the water. In non-conserved spread, the amount of content changes as it enters and passes through a complex network. The model of non-conserved spread can best be represented by a continuously running faucet running through a series of funnels connected by tubes. Here, the amount of water from the original source is infinite. Also, any funnels that have been exposed to the water continue to experience the water even as it passes into successive funnels. The non-conserved model is the most suitable for explaining the transmission of most [[infectious diseases]].

*'''本征向量中心性''' 是度中心性的的一个更加复杂的版本，一个节点的中心性不仅依赖于它的连接数，还取决于这些连接的质量。质量因子由网络邻接矩阵的本征向量决定。

*'''Katz 中心性''' 通过计算某节点与其他可到达节点间最短路径的和来度量。这些路径是有权重的，连接节点与其近邻节点的路径的权重要高于那些与距离其近邻节点较远的节点相连接的路径。
