A regular six-sided polygon and a regular four-sided polygon contain the same five shapes—each are made up of the same four trapezoids and one triangle.
一个规则的六边形和一个规则的四边形包括同样的五个形状，每个都是由同样的梯形和一个三角形组成。
The cross section of the passage is a regular or irregular plane polygon, and then the specific surface area is large and the mass transfer efficiency is high.
通道横截面为规则或不规则平面多边形，因而比表面积大、传质效率高。
In this paper, a method about contour extraction of regular targets in images is proposed, which is based on an improved rectangle fitting method and a polygon fitting method.
采用多边形拟合物体图象边缘轮廓线，即实现从图象到图形的转换的方法，与直接记录原图象数据相比可大大减少轮廓线上所需记录的边缘点的个数，即减少数据量。
