给出了两个相互依赖的网络的级联失效模型，其中功能节点属于大于或等于S的元件。我们从理论上和模拟上发现，在具有随机依赖链的复杂网络中，S=3的相变是一阶的，S=2是连续的。我们还研究了依赖链中具有距离约束r的相互依赖格子，发现r的增加使系统从一个没有相变的区域移动到一个有二阶相变的区域。当r继续增加时，系统在一阶相变中崩塌。每个制度与功能节点的域形成的不同结构相关联。
We present a cascading failure model of two interdependent networks in which functional nodes belong to components of size greater than or equal to s. We find theoretically and via simulation that in complex networks with random dependency links the transition is first order for s >= 3 and continuous for s = 2. We also study interdependent lattices with a distance constraint r in the dependency links and find that increasing r moves the system from a regime without a phase transition to one with a second-order transition. As r continues to increase, the system collapses in a first-order transition. Each regime is associated with a different structure of domain formation of functional nodes.
