中心圆

At the center of this circle, there is always the UC HQ.

而这个圆的中心，就是本部教会。

The point in the middle of a circle is called the center of a circle.

把圆中心的一点叫做圆心，圆心一般用字母 O 表示。

A straight line from the center to the perimeter of a circle (or from the center to the surface of a sphere).

从圆的中心到周界的直线。

Salt Gui - made with porcelain, center of a circle, showing basin-shaped, bottle-shaped or pot-shaped.

盐贵-与瓷器，一个圆的中心，显示盆形，瓶形或壶形。

The diffraction theory of Kirchhoff is applied to the four-pinhole aperture diffraction screens, the intensity, the zero-contour of the real and imaginary parts of complex amplitude and the phase distribution in deep Fresnel diffraction region are simulated, and it is found that the bright spots in interference field show central symmetry distribution. When the observation plane close to the diffraction screen, the zero-value points of light intensity can form line segment, on which the eccentricities of the light intensity isoline are close or equal to 1, the intensity changes very fast on both sides of the zero-line of light intensity.

利用基尔霍夫衍射理论计算了四圆孔径衍射屏在菲涅尔深区形成的的干涉光场的强度、零值线和相位的分布，发现干涉光场亮斑关于中心呈对称分布，在距离衍射屏较近的观察面上，光强值为的零点组成光强零值线段，该线段上光强等值线的离心率都接近或等于1，其两侧的光强值变化非常剧烈。

In recent years, the company's own technology and processing capacity as the basis, have successfully developed a centre of the circle and other volumes filter equipment.

近年来，公司以自身的技术力量和加工能力为依托，相继成功开发了中心管卷圆机等滤清器设备。

Result:The two cases were all cured without lesion reoccurring by the end of following up period within 10 and 13 years.Conclusions:There is a close with congenital of chondroma.The clinical manifestation of chondroma in sinonasal and nasopharyngeal were complex.

结果：1例肿瘤位于均筛窦，破坏上颌窦内侧骨壁突向上颌窦腔及鼻腔；1例其基底位于以圆枕为中心的鼻咽侧壁，病理结果均诊断为软骨瘤，手术切除全部治愈，追踪分别10年和13年无复发。

Circular disk was rotating about an axis tilted from the normal through the center.

圆盘绕一个通过中心与法线方向倾斜的轴转动。

Central cracked circular disk; split Hopkinson pressure bar; dynamic fracture ; dynamic stress intensity factor

中心裂纹圆盘；分离式霍普金森压杆；动态断裂；动态应力强度因子

The fracture toughness testing technique for the central cracked circular disk specimen is given to investigate the fracture behavior of brittle material polymethyl methacrylate under pure mode Ⅰ, pure mode Ⅱ and mixed-mode loadings. The experimental results show that the load distribution angle is always greater than 8° for all different loading conditions.

给出一个中心裂纹圆盘断裂试验的较完整的试验技术，并用此试验技术在岛津材料试验机上对有机玻璃(polymethyl methacrylate， PMMA)这种典型的脆性材料成功地进行纯Ⅰ型、纯Ⅱ型和复合型加载条件下的断裂试验。

I will endeavour to find you some assistance.

At first I only know bruck is the idol of American younglings, afterwards I returned back to Taiwan ,even in Beijing last year ,I saw her poster everywhere, I was so surprised at her charm.

起初我只晓得布鲁克雷德丝是美国少男少女崇拜的偶像，后来回台湾，甚至去年在北京，居然也四处看见她的海报，才惊讶她的魅力之大。
