The planet gear spherical grinder is according to the spherical surface is designed.

行星齿轮球面磨专机是根据球面磨削原理来设计的。

Seismic responses of long-span single-layer and double-layer reticulated spherical shell under wave excitations and uniform excitation s are studied.

本文考虑了地震波的行波效应，采用不同的视波速，对单双层球面网壳结构在行波激励下的反应分别进行了计算分析，并与在一致激励下的地震反应进行对比，考察了两者之间的差异，深入分析了大跨度单双层球面网壳结构在行波激励下的地震反应规律，得出了一些有益于工程实际的重要结论。

It is proved the point-explosion spherical shock wave is a special case of the ellipsoidal wave in theory and by experiment.

论证了点源球面冲击波是旋转椭球面冲击波的特例。

If we define the surface of Earth as being at the mean sea level, we don't get a spheroid or even an ellipsoid.

如果我们把地球表面定义为平均海平面，我们得到的不是球面，也不是椭球面。

As for the spherical radius of 71.2037 mm,the standard error of 472.3 μm can be obtained.

实验结果表明：设计的光学球面自动测量系统可以对大曲率半径光学球面实现高精度测量。

Furthermore, a method is also given to determine projecting image of the first derivative vectors on a sphere under the stereographic projection.

然后，逆投影回球面得到一条球面有理插值PH曲线。

An initial spherical parameterization is firstly constructed by lifting planar parameterization to the sphere through the stereographic projection. Then we introduce an efficient approach based on bary centric coordinate to improve the initial spherical parameterization. At last, a uniform spherical parameterization is generated by a Moebius transformation.

通过立体投影将现有的平面参数化方法推广到球面上，得到一个初始的球面参数化；为了减小变形，引入质心坐标进行全局优化；最后用Moebius变换均匀化最终的球面网格。

Occasionally I turned my looks to the terrestrial globe on my desk and noticed an ant crawling on the globe ceaselessly and round and round; I don't know how long it has been on the ball, perhaps it was brought here by wind.

偶尔目光落到桌上的地球仪：一只蚂蚁不知什么时候被什么风吹到了地球仪上，它沿着球面不断地往前爬，爬了一圈又一圈；在这蚂蚁的二维空间里，球面是无限的，无边无涯。

Then, we present an efficient sampling algorithm on the unit sphere, and the generated point distribution can match the SRBF representation. We are capable of creating images with multiple measured BRDFs under global illumination.

此外，根据球面射基底函的表现形式，我们也提出一种有效的重要性采样方法，其产生出的采样分布可以合球面射基底函所描述的资分布，此方法可以在全域光源照射的环境下，有效地绘制包含多种复杂材质的场景影像。

As for the case n = 3; we also characterize the totallyumbilical spheres and the Veronese surface by a pinching condition for the case n≧4: Analogous to the case n = 3; we then introduce a conformal invariant quantity, and

我们同样考虑n维单位球面中的威尔摩曲面，并藉著某些夹挤的条件对全脐球面与Veronese曲面进行分类。

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。
