针对复杂网络中存在的相继故障问题，给出一个改进的相继故障模型。在基于耦合映像格子的相继故障模型中引入影响因子，将节点间的相互影响反映在节点的状态变化中，并在两种典型网络中进行仿真分析，结果表明具有较大影响因子的节点易引发相继故障，应作为网络风险控制的重要节点。

An improved cascading failure model in complex networks is proposed in this paper . Some impact factors are introduced into the cascading failure model based on coupled map lattices ,thus ,the interrelationship of various nodes can be drawn from their status changing . Simulation analysis in two typical networks shows that ,the node with greater impact factor is easier to suffer cascading failure ,and must be paid more attentions to in networks risk management .
