闭曲面 meaning in English
closed surface
Examples
- Boundary pre - adjustment method for finite - element mesh generation of closed surface
闭曲面有限元网格生成的边界预调整方法 - The computation of three dimensional volume is converted into that of integral of closed surface , which is based on the divergence theory
摘要利用散度定理将体积计算转化为闭曲面上的积分，对曲面进行三角形网格剖分。 - In the case of closed surface , we obtain the following result : theorem 3 . 1 let m be a closed surface with parallel mean curvature direction in r4 ( ) , which admitting an isometric deformation preserving mean curvature
在闭的情况下，我们得到如下结果:定理3 . 1设m是r4 (约中平均曲率方向平行、非脐的闭曲面.若m容有保持平均曲率方向平行、且保平均曲率的等距变形曲面应，则m有常平均曲率 - In 1951 , h . hopf proved , by associating a holomorphic 2 - differential to each constant mean curvature surfaces in r3 , that only compact genus zero surfaces immersed in r3 with constant mean curvature are the round sphere , in chapter two , we consider the same question about the compact 2 - type surfaces of genus zero in s7
1951年， h . hopf发现r ~ 3中每个常平均曲率曲面都伴随一个全纯微分2 -形式，并证明了零亏格的常平均曲率闭曲面一定是r3中的球面.本文的第二章对于犷中零亏格的2型曲面讨论了类似的问题 - Abstract : a new data structure that one link - list was composed of polygon - surface table , edge table and vertex table was proposed to describe the geometry information and topology information of control polyhedron m in the rese arch of modeling with closed surface . compared with other structures which were a pplicable to the work , the structure was understandable , economize and conveniently to modify . after describing the detail of the geometry information , topology inf ormation included in the tables of polygon - surface , edge and vertex , and the poin t - link form of the adjacency multilist between the tables , a concise instance was given in clanguage array
文摘:介绍了在闭曲面造型研究中，为描述控制多面体m的几何信息和拓扑信息而设计使用的一种单链三表的数据结构.与其他适用与描述控制多面体的数据结构相比，该结构在结合了邻接多重表方法后的特点是:关系描述清楚，节省存储空间，方便查找和交互修改形体.在介绍单链中三表(面表、边表、顶点表)所含的几何信息细节、以及单链的三表之间的表示面、边、顶点拓扑关系的指针的邻接多重连接方式之后，本文给出了以c语言数组方式简明描述的数据结构实例
