Any graph's cliping attributes to line cliping finally.It commonly used three kinds of line segment cliping algorithms that mainly included the Cohen-Sutherland algorithm, the midpoint of division algorithm and Liang－Barsky algorithm.

任何图形的裁剪最终都归结于直线段裁剪，常用的直线段裁剪算法主要有Cohen—Sutherland算法、中点分割算法及梁友栋一Barsky算法三种。

Clipping is one of basic problems in computer graphics.

裁剪是计算机图形学中的一个基本问题。

Line clipping is one of the fundamental problems in computer graphics.

By applying closed principal curve learning algorithm,we can obtain a simple polydragon as an approach for every simple closed curve in plane.

本文首先将具有简单封闭曲线特征的闭主曲线学习算法应用于平面有界闭区域图形的边界提取，给出相应的算法。

The major purpose of this article was to illustrate the innovating instruction of the topic-"triangle" for the third graders. From the experience of the classrooms, it is considered that the curriculum is only to instill into children some geometric nouns, such as the sides, the apexes and the angles. A closed graph with three angles is usually to be named as a triangle without thinking about children's understanding of the real meaning.

本文的主要目的乃是针对教学者本身以往在教国小三年级学童的「三角形」这个单元时，自觉只是在灌输孩子一些几何的名词，例如：这个就是边、顶点和角；有三个角的封闭图形就是三角形，并没有去考虑到孩子是否真正的理解这些语词的涵意。
