In this paper, a brief review and evaluation of existing measure methods about the importance of the vertices was given, i.

在曲线简化过程中，一个最基础的问题是如何度量曲线上节点的重要性程度。

Many programs draw objects on the screen with polylines. A polyline is a graphics programmer's term for a multisegment line defined by an array of vertices.

许多程序在屏幕上画出的对象呈折线形，折线是绘图程序的专用术语，专指由一系列顶点定义的多段线条。

This tells Direct3D and the driver that you will be adding vertices and won't be modifying the ones that you previously batched.

这告诉D3D和设备你要添加新的顶点到缓存中，但是不改变原有顶点数据。

This tells Direct3D and the driver that you will be adding vertices and won't be modifying the ones that you divviously batched.

这告诉 D3D 和设备你要添加新的顶点到缓存中，但是不改变原有顶点数据。

A new algorithm for representing conies precisely is presented using the periodic NURBS. The algorithm requires only four control vertices to represent a full circle using a circumscribing square.

本文探讨了用2次周期性NURBS表示闭合圆锥曲线的方法，导出了精确表示椭圆、抛物线和双曲线的条件，并给出了精确表示圆弧的充要条件；提出了用2次NURBS精确表示圆的新方法。

Some necessary conditions are obtained for sequential graphs, regular sequential graphs and Euler sequential graphs; several non-sequential graphs classes are showed for conglutinating graphs. The sequential graphs that contain even cycle with the same vertices have been constructed.

使用这种方法，得到了一般序列图、正则序列图、Euler序列图、圈的粘接序列图和圈的并序列图的必要条件，证明了边数为2k， k是奇数的Euler图是非序列图类，讨论了m个n圈的粘接图中的非序列图类；分析偶圈的特征，构造了偶圈的具有同顶点集的序列母图井给出其序列标号表达式。

The main idea of this algorithm is as following: firstly, the rectangle is classified by the value and position of its vertices; secondly, the rectangle is divided into some mangles through classification; thirdly, trace and render contour on each triangle obtained above.

算法基本思想是：先对矩形网格4个顶点值按照其大小和相互位置关系分类，然后把矩形网格划分为若干个三角形网格，最后在三角形网格内完成等值线的追踪和填充。

There are a lot of technological difficult points involved in NC machining graphic simulating, this thesis has mainly told about the line and arc interpolation algorithm, vertices of triangle mashes modeling, fast inquiry method for solid stock data, the algorithm of intersect the stock with the swept volume of a cutter, the cutter tool real-time removing display and so on.

图形仿真涉及到的技术难点比较多，论文主要对直线、圆弧的插补算法，工件的三角网格建模和显示技术，工件数据的存储和快速查询方法，刀具扫掠体和工件的求交算法，图形的快速局部消隐算法，刀具的动态显示等方面进行了详细的介绍。

And resulted in smaller vertices (5 or 6 floats instead of 11 -12) partially offsetting the additional numbers.

并导致在较小的顶点（5或6花车不是11 -12）部分抵消额外的数字。

Some new notions are defined, such as I-convex sets, I-convex polyhedrons, vertices and so on. And then, based on these new notions, we get a similar conclusion with that of linear programming.

在汪培庄[69]工作的基础上，讨论了更一般的格化线性规划模型，给出了其解集的结构及能求得全体最优解的算法；在方述诚等人

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
