顶点

And then the vertices on the perimeters of the merged face are deleted to further simplify the original meshes model.

然后利用顶点删除法实现超面区域边界的简化，进一步加大原网格模型的简化程度。

It demonstrates the existence of two type distorted MnO〓 octahedra in the Ca-deficient system that the infrared transmission spectra show two stretching phonon modes of MnO〓 octahedra and the second resistivity peak nearly does not change under magnetic field.

根据以上实验结果，我们提出在缺钙稀土锰氧化物体系中存在两类不同的畸变MnO〓八面体：一类是Mn〓离子的JT效应导致的MnO〓八面体畸变；另一类是Ca位空穴引起的MnO〓八面体悬挂顶点氧导致的MnO〓八面体畸变。

But the only zones in which the moon passes the zenith, the point directly over the head of the spectator, are between the twenty-eighth parallels are the equator.

但是，月亮经过天顶点，也就是说它能够爬上观测者的头顶的地方，必须位于地球赤道和南北纬二十八度之间的地带。

The conflict marked the culmination of tension between the two powers following Prussia's rise to dominance in Germany, still a loose federation of quasi-independent territories.

战前，普鲁士在近乎松散的德意志联邦中日益强大，处于统治地位。这一战争的爆发使两国间一触即发的紧张局势最终达到顶点。

3 And 3-4 is shown in Fig. 3-5;note that in this graph all idea of space and distance has gone,although we can still tell at a glance which points are joined by a wire or a road.

图3-3和图3-4的另一同构图如图3-5所示；注意此图中的所有有关空间和距离的概念都不复存在了，虽然我们仍然可以一眼看出哪些顶点被导线或公路所连接。

A try square with an adjustable sliding head.

有一个可以调节的滑行顶点的检验角尺。

Firstly, trace region boundary and obtains chain code to construct tree structure of contours through a pixel vertex matrix.

其次设计了边界跟踪自动机，利用自动机的输出获得边界的顶点链码，自动机跟踪所有图像边界的同时生成围线树结构。

The culminating point of this sweep of walls was the Papal gate, that is to say, near the present site of the Pantheon.

这道弧形城墙的中心顶点是教皇门，即大致上相当于先贤祠的现在位置。

Venus will appear to arise from the pyramid's apex on that day, while an astonishing cosmological alignment of the earth, sun and the plane of the galaxy takes place.

金星将出现产生于金字塔的顶点在这一天，同时拥有惊人的宇宙对准地球，太阳和飞机银河发生。

The achievements are listed below:1. Algorithms are proposed for tracing boundary and extracting vertex chain code and obtaining the tree structure of contours from 8-adjacent and 4-adjacent images.

本文的工作及研究成果可以归纳为： 1、分别就八近邻图像和四近邻图像给出了边界跟踪、顶点链码抽取及围线树结构的生成算法。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
