查询词典 simple polyhedron

Existing methods can't be used for recognizing simple polyhedron.

已有的识别方法对于简单平面立体的识别均不能凑效。

Last,a new method is presented to recognize simple polyhedron from a line drawing.The method filters the candidate database before matching line drawing and model,so the recognition efficiency is improved greatly.

提出一种从单幅线图识别简单平面立体的新方法，该方法在匹配待识别线图与模型结点之前，先用拓扑信息进行候选模型的筛选，大大提高了识别的效率。

In this paper,three problems are researched.First,a method for recognizing triangle and quadrangle is introduced based on geometry and angle constraint.Then Attribute Relation Graph is employed to describe simple polyhedron and line drawing.

依据投影几何中的距离约束和角度约束，给出了三边形和平行四边形的识别方法；提出用属性关系图表示平面立体和线图，该描述方法是一种结合表面特征和几何特征的方法。

The neighbor-ing two Gd3+ ions are connected by two simple bridged carboxyl groups and a μ2-bridging carboxylgroup. Each G-d3+ ion is simuetaneosly coordinated by two water molecules. So the coordination num-ber of Gd3+ is nine, forming a coordination polyhedron of distorted mono capped square antiprism.

相邻Gd3+离子通过2个简单羧基桥和1个μ2羧基桥联结起来，还有2个水分子配位于每个Gd3+离子，所以Gd3+的配位数为9，形成变形的单帽四方反棱柱体。

In this article, we introduce the oriented volume concept of simple tetrahedral, and get the computation formula for polyhedron at last.

引入了简单四面体的有向体积概念，最后得多面体体积计算公式。
