顶点

In general,given two vertices V and W in a graph,it is not always possible to find a path connecting them;such a path will exist only when the graph is 'in one piece'.

D8 |一般而言，给定图的两个顶点V和W并非总能找到连接它们的路；只有当图是"在一块中"时，这样的路才存在。

Comment: A graph is CONNECTED if there is a path connecting every two vertices.

说明：如果任意两个顶点之间都存在路径相连，那么称这个图为"连接图"

In general,given two vertices V and W in a graph,it is not always possible to find a path connecting them（see Fig.3-9）;such a path will exist only when the graph is"in one piece".

一般而言，给定图的两个顶点V和W并非总能找到连接它们的路（如图3-9所示）；只有图"在一块之中"时，这样的路才存在。

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）.

在图论中，人们还对树感兴趣，树是每一对顶点间只有一条路的连通图。

First, the relative curvature of a certain curve at its first end and the directional angle of the first port tangent vector of that curve as well as the weight factor of the interpolation curve are given, then all the other control vertexes can be gotten by using the conditions of G continuity, and a method to construct transitional curves is also introduced so that we can get the closed interpolation curve which achieves G continuity globally.

首先给定某段曲线的首端相对曲率和该段曲线的首端切矢量的方向角以及插值曲线的权因子，然后利用G2连续条件求出其余控制顶点，并给出了构造过渡曲线的方法，得到了G2连续的闭插值曲线。

For some being serviced buffer, the continuous limit processing time is selected such that the continuous state slides onto a 1-dimension manifold spanned by two succession vertexes of the periodic orbit.

当Server服务于一个Buffer时，以此状态下在连续周期轨道上对应的2个顶点张成的一维线形子流型为滑动目标，仅通过系统许可的对极限连续处理时间的控制，使系统镇定于周期轨道。

In this paper, the method, which is based on the theory of envelope and continuous map, is investigated.

文中用此方法分析了一些曲线的重要几何性质，即曲线段上含有尖点、重结点和拐点以及不含这些点的用控制顶点相对位置表示的充分必要条件。

To the plate with low contradistinction, the features and can locate the vertexes and the lines of the character area instead of those of the plate.

向板对比低的特点和可以找到顶点和行的性质而不是那些地区的板块。

Both the first and second movements demonstrate the composer's contrapuntal ingenuity in combining themes; the capstone of the second is an extended fugato comprising the central section of a three-part design.

第一和第二乐章显示出了作曲家在主题对比上对位的精巧性。第二乐章的顶点是一个包含了三部体裁的中部的扩展性赋格段。

This paper considers a absolute stability problem for a class of uncertain systems that the linear part is the convex combination of finite vertex models ,and the nonlinear part is a nonlinear sector.

本文考虑一类不确定系统的绝对稳定性问题，系统的线性部分乃顶点模型的凸组合，非线性部分是一个非线性扇区如通常绝对稳定性问题中那样。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
