定向图 meaning in English
beam pattern
directed graph
directional diagram
orientation chart
orientation map
oriented graph
Examples
- An orientation of a complete graph is called a tournament .
完全图的定向图称为竞赛图。 - An upper bound of the spectral radius on the oriented graphs
定向图的谱半径的一个上界 - Listing 5 presents a simple directed graph consisting of three nodes in dot notation
清单5给出了一个简单的定向图（ directed graph ） ，其中包含3个节点。 - A uniquely pancyclic digraph is a digraph which has exactly one directed cycle of each length l , for 3 l v , where v is the number of vertices of the digraph
一个唯一泛圈有向图是一个定向图，且对3 l v的每个l ，它恰好有一个长为l的有向圈，这里的v表示有向图的顶点数。 - In 1973 , r . c . entringer raised the following question : determine which simple graphs g have exactly one cycle of each length l , 3 l v . in this paper , entringer ' s problem is extended to directed graphs and get serveral results about uniquely pancyclic digraphs
Entringer提出了确定唯一泛圈图的问题，即确定简单图g使得对3 l v的每个l恰有一个长为l的圈。本文将entringer这个问题推广到定向图中，研究了唯一泛圈有向图的若干问题。
