A tall, four-sided shaft of stone, usually tapered and monolithic, that rises to a point.

方尖石碑升到一点的四面体高塔或碑石，常为尖顶和由整块石料的

Is considered as five tetrahedra sharing a commonedge formed by the two capped atoms. This structure is very stable, and has lowreactivity.

我们的结果也支持〓是由五个正四面体共用一条边连接而成的一种结构，这种结构非常稳定，从而化学活性也很低。

To fill the isosurface with tetrahedra, cubes either intersecting with or lying within the isosurface are decomposed by using the precomputed stencils.

然后，对栅格中所有位于等值面之内或与等值面相交的立方体，用预定义的模板分解成四面体单元。

At first, a simple algebraic method is appied to generated O-H type three dimensional meshes, then the meshes are devided into tetrahedra meshes.

首先应用一种简单的代数方法生成了O-H型网格，然后，将其剖分为四面体网格，从而完成了简化航天飞机跨音速绕流的数值模拟。

A novel paddlewheel type compound 2 containing trinuclear cobalt cluster has been obtained. Co3 clusters are connected by PO4 tetrahedra and 4-pya ligands to form a 3D network structure.

另外，一个新奇的含有三核钴簇的桨轮状化合物2被合成，Co3簇被PO4四面体和4-pya配体连接成三维网状结构。

Tudy on the structure and stablities of anion cluster(SiO_2)_nX~-3MR (three-membered ring) structure, 2MR (two-membered ring) linear chain structure and pseudotetrahedral cage structure have been proposed for the anion cluster (SiO_2)_nX~-(n=1~5 X=_, 0, OH).

iO_2_nX~-离子团簇结构和稳定性的理论研究主要研究(SiO_2)_nX~-(n=1～5 X=_，O，OH)离子团簇的三类典型结构(三元环结构、二元环链状结构和四面体笼状结构)。

For nanodiamonds, the Raman spectra of both series of octahedral and tetrahedral diamonds show an evidence of the unique peak at 1332 cm-1, which was previously observed in experimental Raman spectra of diamond.

这些性质整体而言呈现了收敛的行为。2。对於奈米钻石，我们计算了四面体和八面体结构之奈米钻石的拉曼光谱。

Chapter three explains every step to establish four-dimension reseau specifically, including demonstration and flow chart.

在第三章里面，详细的说明了建立四面体网格的每一个步骤，其中附有说明图和流程图。

We chose the advancing-front Delaunay algorithm because it can be parallelized easily and is convenient for magnanimity data.

DTETAD突破了传统的Delaunay四面体划分的限制，为网格划分等实际应用提供了理论基础。

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.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
