中文摘要：

对相互依存网络的研究现状进行综述．介绍了相互依存网络的概念和模型，并简单描述了相互依存网络上的级联失效过程．根据网络的拓扑结构，分别从一对一连接关系的相互依存网，多对多连接关系的相互依存网，多层网络系统以及无标度网络构成的相互依存网络四个部分介绍相互依存网的鲁棒性研究，及其鲁棒性的提升方法。最后对相互依存网络的研究现状进行小结并对未来发展做出展望。

英文摘要：

A briefly review about the interdependent networks is given in this article. The concept and models of interdependent networks are introduced. The failure of nodes in one network may trigger cascading failures and catastrophic consequences. According to the topology of the system, the existing empirical research on the robustness of interdependent networks is reviewed from four aspects： the systems with one-to-one connection relationship, the systems with multiple dependencies, the systems of networks, and the scale-free networks. The existing methods for enhancing network robustness are given. At last, the research on interdependent networks is briefly summarized.
