几何学图形的

In geometry a polygon is traditionally aplane figure that is bounded by a closed path or circuit, composed of a finite sequence of straight line segments.

在几何学中， polygon是一个传统的平面图形由封闭路径及环形，由有限的直线规律地构成。

The elegancy and singularity of fractal pictures attract the attention of more and more fractal fans.Fractality is not only used for enjoyment,but also is a new research direction of geometry which is the research on anomalous geometry objects.

分形图形的优美与玄妙吸引着越来越多的分形爱好者，它不仅仅是用来欣赏的，而且代表着几何学的一个新的研究方向，即对非规整几何对象的研究［1］。

Top predators in the Red Sea, geometric moray eels slither out of a hideout on the sea floor.

顶端掠食者在红海，几何学图形的海鳗鱼不稳定的滑行来自藏身处的海底。

A parametric study graphic nature of the projection, that is, they read the projective transformation, remained the same graphic nature of the geometry, the branches. 2D projective transformation is a more common transform method, used in the camera lens of the camera plane, and applied to various fields of study.

射影几何是研究图形的射影性质，即它们经过射影变换后，依然保持不变的图形性质的几何学分支学科。2D射影变换是一种较为常见的变换方法，发生在用透视摄像机对平面摄像的时候，并应用于各个研究领域。

On the basis of kinematics and geometry principle, a mathematical model for the crank rocker arm mechanism was established.

从运动学和几何学原理出发，建立了曲柄摇杆机构的数学模型，得出了工件中心点的瞬时速度和运动轨迹，并开发了相应的计算机动态仿真软件，以图形的形式显示了工件中心点运动轨迹曲线以及瞬时速度曲线。

The book review first vector and matrix algebra, the basic concepts and then described in detail geometry involved in a variety of two-dimensional graphics and three-dimensional geometric measurement of the object, the intersection of various algorithms and other issues, and provides information on the theme of a large number of computational geometry materials in order to facilitate quick reference.

全书先复习了向量和矩阵代数的基本概念，而后详细地描述了图形几何学涉及的各种二维和三维对象的几何测量、相交等问题的各种算法，并提供了关于计算几何学主题的大量材料以便于快速参考。

Through proof and using geometric methods, this paper presents some conclusions about orthographies, projective characteristics and position in space of oblique line with equal dip angles to the planes of projection .

运用几何学，通过证明对一般位置等倾直线投影图形、投影特性及空间各种各样的等倾直线位置进行推导、归纳，从中总结出一般规律，最后给出结论。

And his entry for the most important competition of his life was a series of sketches of triangles and random parabolas, free shapes bounded by "curves in space geometrically undefined".

在他职业生涯最重要的那次比赛中，他的参赛作品是一连串令人目眩的形态组合图：三角形、恣肆凌乱的抛物线以及未能在空间几何学上明确定义的无数曲线，这些曲线环绕着看似信手涂鸦而来的图形。

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。
