- dominating pair of vertices 控制点对
- dominated pair of vertices 受控点对
- If two edges of a graph are incident to the same pair of vertices, then these two edges are called parallel edges. 如果一个图的两条边关联于同一对顶点，则这两条边称为平行边。
- One quadrilateral is defined for each pair of vertices presented after the first pair. 一个四边形是由这一对顶点和前面一对顶点构成的。
- For every pair of vertices $u,v$ in an oriented graph, a $u$-$v$ $geodesic$ is a shortest directed path from $u$ to $v$. 本篇论文的主要内容，在于考虑若干个与图形有关的捷径问题。
- A directed graph, or digraph G consists of a finite nonempty set of vertices V, and a finite set of edges E, where an edge is an ordered pair of vertices in V. 有向图，或图克组成的有限非空子集的顶点V和有限的一套边英，那里的优势是下令对顶点在五顶点也称为节点。
- I bought a pair of tan leather shoes the other day. 前几天我买了双棕褐色的皮鞋。
- In Graph Theory,we shall also be interested in connected graphs in which there is only one path connecting each pair of vertices;such graphs are called trees(generalizing the idea of a family tree). 一个图如果能够按这种方式(同构关系)重画为一个没有交叉线的图成为平面图，这种图在图论中极端重要。
- Don't mix up this pair of synonyms. 别把这两个近义词混淆了。

- This pair of scales is not in equilibrium. 这个天平不平衡。
- If the edges are ordered pairs of vertices then we get the notions of a directed graph and directed multigraph. 如果边都是顶点的有序对,则得到有向图和有向重图的概念。
