The topological relationship of nodes and road sections in road network was expressed by adjacent node relation matrix and adjacent node weight matrix, which saved the storage space.

采用邻接结点关系矩阵和邻接结点权矩阵表达路网中结点和路段的拓扑关系，减少了路网的存储空间。

The power distribution network can be simplified as switch node network. By applying electric network graphic theory its adjacent node matrix and node information matrix can be derived.

忽略电网中的其它元件，将电网从结构上简化为以开关当作节点的网络，应用电工网络图论原理建立节点的邻接矩阵和节点信息矩阵。

Each node contained a small processor, a sensor and a low-powered radio with just enough power to talk to adjacent nodes and the network was just smart enough to reconfigure itself to reroute data whenever one node got damaged.
