4·These electrons get funnelled into a metal spherical receiver to produce a current, which generates the wire's magnetic field - making the system self-sustaining.
这些电子被引入一个球形金属收集器以产生电流，继而产生线圈的磁场——这样这个系统就可以自我维持了。
5·Among the remains, the team noticed a spherical bone, called a basioccipital condyle, found in all mammals and reptiles that joins the base of the skull to the spinal cord.
该团队在遗骨中发现一个称为枕骨髁的球形骨，这是所有哺乳动物和爬行动物身体中连接颅底和脊髓的部分。
1·In other cases, a spherical model is used, and the primary distance calculation used is the great-circle distance (see Resources).
在其他情况下使用球面模型，所使用的主要距离计算为大圆弧长(参见参考资料)。
2·The spherical model is better-suited when distances are further apart and more accuracy is needed.
当两点之间的距离相隔很远和要求更高的准确度时，需要使用球面模型。
3·But, that spherical thing with a little slit going twisting into it will actually have boundary my loop.
这个有裂痕的球面，确实有一个边界是该回路。
4·Now, thanks to a new collaboration with NASA, WorldWide Telescope has produced the most detailed spherical image of the heavens to date, along with a new 3-D, true color map of the surface of Mars.
现在，由于与美国航空航天局（NASA）的一项新合作，微软世界望远镜做出了迄今为止最详细的宇宙球面图，还有新的火星表面3D真彩地图。
5·The splot command is Cartesian by default but can also support spherical and cylindrical coordinates.

5·We have rectangular coordinates, we have cylindrical coordinates and we have spherical coordinates.
我们有直角坐标系，有柱坐标系和球坐标系。
1·Think of a three-dimensional spherical black hole that's copied and stacked out in one direction to create an oblong shape.
设想一个三维的球状黑洞，把它复制和堆放在一个方向上，就会构成一个长方形的形状。
2·Since the volume of the spherical universe is much bigger than its outer surface, how could this be true?
由于球状宇宙的容量远远大于其表面积，这一切怎么可能呢？
