几何结构

John Wheeler at Princeton University thinks of this as a foamy, sub-structure to space where the geometry of space twists and contorts so that far flung regions of space may suddenly find themselves connected by 'wormholes' which constantly appear and disappear within 10(-43) seconds.

普林斯顿大学的John Wheeler认为这是空间的泡沫状亚结构，其中的几何空间扭曲变形，使得被远远抛出的空间在虫洞处与自身结合，而虫洞的反复出现和消失都发生在10（-43）秒之内。

According to experimental results in which the dehydrogenating properties of MgH2 systems were improved by addition of NiF2 as catalyst, the energy to remove H atoms, the geometry and electronic structure of MgH2 systems were calculated by using Dmol 4.1 program based on the density functional theory, and the mechanism of improved properties on Ni doped MgH2 systems were also analyzed.

摘 要：采用基于密度泛函理论的Dmol 4.1程序包，通过计算移走H原子所需能量及几何、电子结构的改变，对Ni掺杂MgH2体系解氢性能的机理进行探讨。

In this paper, Gray code and line shifting structure light were projected to the object. Then the distortion images were got which can reconstruct the 3D model: The images space was divvied into 64 cycles by six sequence image the acquisition, the whole scanning plane has been covered by the mobile fringes, which has been cycled 20 times. With the parameters of two calibration cameras , the image pixels has been matched by the principle of geometry.

本论文的主要研究内容是利用格雷码加线移结构光对物体进行投影，再经摄像机采集到畸变的图像，结合相关算法以实现对物体的三维重构：摄像机采集到的6幅图像序列形成的格雷码将图像空间划分为64个周期，通过20次线条纹的移动完成对整个扫描平面的覆盖，在已获得两摄像机标定参数基础上，结合对极几何原理完成左右图像像素点的匹配。

Both eddies have similar scales to the structure of combustion chamber.

涡团大小与结构本身的几何尺寸具有相比拟的尺度。

The results show that the HOMOs were mainly localized on C60, while the LUMOs were mainly localized on the substituents. This indicated that the electrons were easy to transfer from the occupied orbitals of donors to the virtual orbital of the acceptors, i.e.

最后，我们分别运用量子化学半经验AM1和密度泛函B3LYP/6-31G计算方法对目标化合物进行了结构优化，得到了这些分子的稳定几何构型。

At this stage, the deposited Mn either cooperates into the 3D Pb capped Mn islands, and promotes the upright growth of the 3D Pb capped Mn islands, or nucleates and growths on the MnTe superstructure area.

这个阶段中，沉积的Mn原子部分在MnTe超结构区域成核生长；部分则吸附于Pb覆盖的Mn岛表面，促进岛的纵向生长，但并不改变岛的其他性质（包括岛的横向大小、几何形状及表层成分等）。

The authors introduce the geometrical characteristics and topological characteristics describe each junction of ARG,so the algorithm can not only recognize polyhedrons of different shape but also distinguish between polyhedrons that are of the same shape but their sizes and proportions are different.

结合几何特征和拓扑特征表示ARG中的每个结点，不仅能识别不同形状的目标，而且能把拓扑结构相同，但各部分大小、比例不相同的目标区分开。

Predating CAD, this geometric linear- and arc-based approach evolved out of the mental constructs of design technique, industrial fabrication, and reproduction of the objects of the 20th Century.

早期的CAD，是以心理结构，工业制造和20世纪物质再生产演化而来几何直线和圆弧。

That's been one of the keys because not only have they trimmed the tubular steel chassis of weight, but they've recalculated and realigned some of its geometry and switched to a stiffer, lighter steel as well.

这就是我的关键因素之一，因为他们不仅缩减了钢管底盘的重量，但他们已经重新计算和调整它的一些几何和转为严厉，轻钢结构，以及。

In case of morphological change, the deactivated catalysts can be partly renewed by impregnating with 12%〓SO〓 solution, in which most of the components can the redissolved and redried and reactivated.

根据对V-K-S-P／SiO〓催化剂综合研究分析，认为影响苯酐收率的主要因素有，活性体在反应状态下所处的相态，催化剂表面V〓、V〓的分布及其与助剂间的配位环境，催化剂表面几何形貌与结构。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
