顶点

And consequently, if a vertex has no normal vector

顶点。因此，如果没有一个顶点法向量

Continuing above curse, then we can get its optimum solution, that is to say, starting from some feasible vertex, we will get the optimum solution of some linear programming problem after finite times transition of vertex along edge of feasible region.

这就是说，自可行域的某顶点出发，沿可行域的棱经过若干次可行域顶点的转移后，就能得到线性规划问题的最优解。

The vertex is ordered pair composed of agent and autonomic grid service.The graph is constructed by layers of the vertex on mapping from task posets to service set.

图中的顶点是由Agent和自主网格服务组成的序偶，构造算法由任务偏序集到服务集的映射，逐层构造图中的顶点。

A configuration is a connected cluster of vertices of a plane graph together with the degrees of the vertices.

一个构形是面图的一连串连通的顶点与这些顶点的度。

A new feature angle criterion and local greedy triangulation method are presented to simplify vertexes of smooth polyhedral model.

提出了顶点的特征角定义方法、特征角准则及删除顶点后对遗留空洞的局部贪婪剖分方法，解决了多面体表示的光滑曲面模型的简化问题。

The paper improves it in the following two aspects by analyzing and studying the basic principles and procedures of Dijkstra primary algorithm.

文章通过对Dijkstra原始算法的基本原理和步骤进行分析研究，做如下改进：1、从已通过顶点集到未通过顶点集的可能存在的多条最短路径中，不丢弃任何一条最短路径。

The glBegin and glEnd functions delimit the vertices of a primitive or a group of like primitives.

glBegin 和 glEnd 的函数限定了初始的一些顶点或者初始的成组的一些顶点的位置。

To decompose prismoid subject into sweepable sub-volumes, the source vertices project into target surface and decompose target surface to many subdomains. The virtual surfaces are found by linking opposite vertices from source surface and target surface, finally cut volume to sub-volumes. It is also designed spheriform decomposition based on geometry character.

虚拟分解主要是通过将棱柱体的源曲面边界顶点映射到目标曲面，将目标曲面划分成和源曲面一一对应的区域，连接对应的顶点建立虚拟剖分曲面，利用虚拟曲面将复杂的几何体剖分成子几何体。

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。

A 4 regular Hamiltonian planar map is a plannar map which is both 4 regular and Hamilitonian. A nearly 4 regular map is such a map that all of its vertices but the root vertex are 4 valent.

若一个平面地图的所有顶点是四次的，且又是哈密尔顿地图，则称该平面地图为四正则哈密尔顿平面图一个地图是近四正则的，是指除去根点外，其余顶点的次均为四。

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。
