本文主要讨论代数图论中的两个问题-2度Cayley有向图的正规性和紧图。

The double2arc tournament is a digraph in which each pair of vertices are joined by two arcs.

双弧竞赛图是任意两点间恰有两条弧连接的有向图。

Transitions have a sense of direction and hence a process forms a directed graph.

转移是有向的，因此，流程形成了一个有向图。

In order to develop a new method for creating such an object normal form, the meaning of a vertex of the directed graph is extended, such that it is not only a simple vertex, but also a directed graph.

为了研究新的对象范式生成方法，对有向图顶点的含义进行了扩充，使其不仅可以是一个简单的顶点，还可以是一个有向图。

Finding the shortest path in a directed network is the basic problem in graph theory.

有向图中的最短路径问题是图论应用的基本问题，对很多实际问题很有指导意义。

Further more, in order to express machining conditions with graph theory a new theory and space network are proposed, the decision of machining plan is made with incidence matrix.

提出了推理过程的具体算法，从而进一步提出了用图论来表达加工空间状态网络图，以及用有向图的关联矩阵进行加工方案的决策等新的理论和方法。

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。

So with the adjacency matrix that has n vertices of a directed graph n2 units needed to store the adjacency matrix; on n vertices have an undirected graph Zexu into upper triangle, and only ...

因此用邻接矩阵来表示一个具有n个顶点的有向图时需要n2个单位来存储邻接矩阵；对有n个顶点的无向图则需存入上三角形，故只。。。

To enhance security in Ad-Hoc networks,it is important to evaluate the trustworthiness of other nodes without centralized authorities.In this work,authors focus on the evaluation of trust evidence in Ad Hoc networks.First,the authors introduce the metrics of the trust,the evaluation process is modeled as a path problem on a directed graph,where nodes represent entities,and edges represent trust relations.Using the theory of semirings,a trust evaluation model based on semiring（TD-SEMIRING） is developed,then two nodes can establish an indirect trust relation without previous direct interaction and introduce the application of this model in route election.At last,the feasibility of this model is analyzed.

讨论了对可信事件的评估：首先介绍了可信的相关概念和相关的特性；接着评估过程被建模成一个在有向图寻找最短路径的问题，在该有向图中结点表示实体或者用户，边表示可信关系，通过使用半环理论，建立了一个基于半环的可信性评估模型TD-SEMIRING，在两个以前没有进行相互操作的实体之间建立间接的可信关系，介绍了这个模型在路由选择当中的应用；最后，通过仿真实验，验证、分析了该模型的有效性。

In this paper, we try to find and prove some characters on the paths and cycles in simple graphs, in digraphs and in colored graphs. Some satisfied results are gained.

在这篇文章中，我们尝试着在简单图、有向图、染色图领域对图的路和圈的某些特性进行刻画，得出了一些令人满意的结果。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
