| 摘 要： | 给出球面"似均匀格网"概念的内涵,并介绍3种常用的球面似均匀格网(三角形格网、菱形格网和六边形格网)的剖分方法.从几何上分析3种格网的单元特征及不同格网在不同领域的应用优势.通过对比得出3种格网的特征对照表及相互关系,即:三角形格网是最基本的球面剖分格网,球面六边形格网和菱形格网可以通过球面三角格网来生成,且这3种剖分格网各有优缺点并在一定条件下可以相互转换.

| Abstract: | Firstly,the connotation of "near-equal grid" on spherical surface is presented in this paper,the partition methods of three common near-equal grids on spherical facet,such as triangular,diamond,and hexagon,are introduced in details.From geometry,their unit properties and advantages in different applied fields are analyzed deeply.In the end,property contrasting table and relationships among the common near-equal grids on spherical facet are given.The conclusion is that triangular is the most basic grid of al... |
