查询词典 tetrahedra

The effective region is combined by all the effective triangles or tetrahedra whose circumcircle contains the inserted vertex.

在二维方面，插点之有效区域乃指网格区域内之所有三角形外接圆或四面体外接球包含此点之三角形或四面体集合。

The connecting of neighbour tetrahedra n wit h common vertex angle forms M—O layer,and the connection of neighbour o ctahedran with common edge or plane forms Al—O layer.

偏岭石结构中近邻四面体与四面体共顶连接构成M—O层，八面体与八面体共棱或共面连接构成Al—O层；而四面体与八面体通过不规则的共顶连接构成近程层状结构。

Upon the addition of CdS into the GeS2-Ga2S3 system, the number of the metal-metal bonds and edge-shared GaS4/2 tetrahedra decreases, resulting in the formation of corner-shared tetrahedra with non-bridging sulfurs.

随着CdS逐渐加入到GeS_2-Ga_2S_3玻璃中，金属-金属键和共边连接的GaS_(4／2)四面体逐渐减少，导致相应共角连接四面体和非桥硫的出现和增加。

In thesegermanates, framework are fOrmed by GeO5 trigonaI bipyramids or GeO6 octahedra,as we1l as GeO4 tetrahedra.

在这些锗酸盐结构中，骨架构成除了GeO4四面体外，还有GeO5三角双锥、GeO6八面体，这预示着锗酸盐分子筛可能具有更丰富的拓扑结构。

This causes the tetrahedra and resulting ray trace to be incorrect.

这会导致四面体和光线跟踪的结果不正确。

In a similar way, a three-dimensional truss can be built up of tetrahedra.

采用类似的疗法，空间架可以由四面体构成。

If two tetrahedra coincide after suitable reflection and rotation, we regard them to

的四面体可以有多少个同的形？（如果个四面体经适当的反射和旋转

In a similar way, a three-d imensional truss can be built up of tetrahedra

Marching cubes algorithm is a classical algorithm to extract iso-surface from regular volume data, and marching tetrahedra algorithm is improved based on MC algorithm.

Marching Cubes算法是基于规则体数据抽取等值面的经典算法，而Marching Tetrahedra算法是MC算法的改进和变型。

It was found that the inorphology ofsulfates is related to the orientation of tetrahedral [SO4]2- in the crystal, i.e., the faces, the edges and faees of the tetrahedra normal to, are expected to grow slowly and observed in final form; in contrast, the faces, the vextices of the tetrahedra pointing to, usually grow fast, and will disappear.

晶体的结晶形貌与[SO4]2-四面体在晶体中的结晶方位密切相关，四面体的面和棱的法线（ L 2）所对向的晶面，生长速率慢，顽强显露，均属晶体的板面；四面体的顶角所指向的晶面，生长速率快，显露面积小，经常消失。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
