如果网络中有许多连接的节点倾向于连接到其他有许多连接的节点，则网络被称为表现出交替混合。在这里，我们测量了各种网络中的混合模式，发现社交网络大多是混合的，但技术和生物网络往往是分离的。我们提出了一个模型的一个混合网络，我们研究分析和数值。在这个模型中，我们发现，网络更容易渗透，如果他们是独立的，他们也更强大的顶点删除。
A network is said to show assortative mixing if the nodes in the network that have many connections tend to be connected to other nodes with many connections. Here we measure mixing patterns in a variety of networks and find that social networks are mostly assortatively mixed, but that technological and biological networks tend to be disassortative. We propose a model of an assortatively mixed network, which we study both analytically and numerically. Within this model we find that networks percolate more easily if they are assortative and that they are also more robust to vertex removal.
