This paper chooses some simple knowledge in the transformation of surface figures and the concept of group, sphere geometry.

但是我们现行的几何教材中，却没有安排现代数学的内容，也没有安排具实际意义的球面几何内容。

Quantitative analysis of the EXAFS spectra showed that the microscopic structure of Znon anatase TiO2 is four coordinate complex, and there are at least two types of bonding based on the average Ti-Zn distances in the second sphere. Two different geometry configurations of single-corner and double-corner for adsorption on the (101) surface cluster were calculated using DFT method.

EXAFS结果表明，Zn在吸附时由自由水合状态下的Zn-O六配位八面体结构向四配位四面体结构转化，中心Zn原子的第二配位层存在两种不同的Zn-Ti距离（R1=0.371和R2=0.332nm）。

In the filed of thermal conduction,traditional meso-mechanics model are mainly based on particle of typical geometry such as sphere or ellipsoid,and a generally adopted premise is the assumption of perfect contact conditions at constituent interfaces.The literature on composite materials lacks today a proper theoretical framework permitting a thorough study of the conduction problem for composites with particles of irregular geometry such as polygon or arbitrary shape in the presence of a thermal contact resistance.

利用细观力学的理论和方法预测和分析复合材料的等效性能，揭示其细观结构与其等效性能的关系，为复合材料设计和性能评价提供理论依据和系统的分析方法，是现代细观力学研究中十分重要的研究课题。

The voltage distribution of Y-type insulator strings for AC/DC 500 kV transmission line is measured by sphere gap method and corresponding measures are adopted to reduce the impacts of environmental factors on measured results, thus the voltage distribution curve of Y-type insulator strings under AC/DC 500 kV conditions.

采用球隙法测量了交、直流500 kV输电线路中Y型串绝缘子的电压分布，采取相应措施减小了环境因素对测量结果的影响，得到了交、直流500 kV电压下Y型串的电压分布曲线。

Private space is one's private circle and secret sphere.

私人空间即个人领域，指个人的隐秘范围。

A circle dividing a sphere or other surface into two usually equal and symmetrical parts.

把一个球体或其他的表面分成两个大抵相等和均匀的部分的圆圈。

A half of a sphere bounded by a great circle.

半球：一个巨大圆周所包围的球体的一半

Deviating from a square or circle or sphere by being elongated in one direction.

通过向一个方向延长正方形、圆形或球形而得到的。

A straight line segment passing through the center of a figure,especially of a circle or sphere,and terminating at the periphery.

直径穿过一图形，特别是圆形或球形的中心到圆周结束的直线段未受干扰的物体继续沿直线匀速前进。

The wisdom of the ignorant somewhat resembles the instinct of animals; it is diffused in but a very narrow sphere, but within that circle it acts with vigor, uniformity and success.

无知者的智慧有点像动物的本能；它只存在于狭小的领域，但是只要在那个范围之内，它又猛又准，所向披靡。

More direct, directer ; most direct, directest

径直的，笔直的

Do you know how to use a chain saw?

你知道如何使用链锯吗？
