如果宇宙的时空像球体表面一样正向弯曲，平行的光线就会交合在一起。
If the universe's space-time is positively curved, like the surface of a sphere, parallel beams would come together.
在球体表面上的一条直线，就是你可能画出的最大圆，就像是赤道或经度线。
And on the surface of a sphere, a straight line is the biggest possible circle you can draw.
在西太平洋中，星球地势起伏的对称受到破坏，那里的地球体表面受到抬升。
The symmetry of the planetary relief is broken in the western Pacific where the geoid surface is uplifted.
至此开始形成的就只会是锂磷酸铁，通过控制环境，研究人员能够使球体表面为玻璃质而非晶质。
From then on the growing sphere is just lithium phosphate and, by manipulating the conditions, the researchers were able to make the coating glassy rather than crystalline.
在球运行路径的某一点(10米处，或人墙的位置)球的速度下降，使空气在球体表面形成较稳定的层流。
Some way into its path - perhaps around the 10 m mark (or at about the position of the wall of defenders) - the ball's velocity dropped such that it entered the laminar flow regime.
地球椭球体表面是曲面，而地图通常要绘制在平面图纸上，因此制图时首先要把曲面展为平面。
Earth is an ellipsoid and its surface is curved, but the maps are usually drawn to the floor plan on paper. So before drawing you must spread the curved surface surface to the plane first.
为了令正二十面体的外形更接近球体，我们把它的面分解成更小的面，并将更多的端点升到球体表面。
In order to improve the roundness of the icosahedron, its surfaces are divided into smaller ones and more points are raised to the surface of the sphere.
火星的运动仅仅是一个球体表面上的一个发光点的运动。尽管它在轨道上旋转，实际却是没有什么变化。
The movement of Mars is merely the movement of a luminous spot on the surface of a sphere , which, although it rotates on its axis, does not actually move anywhere.
的确，四元数支持球形线性插值(SLERP)，那意味着点沿着球体表面传播就像他们从一个方位移到另外一个一样。
Indeed, quaternions support spherical linear interpolation (abbreviated as SLERP), which means that points travel along the surface of a sphere as they are moved from one orientation to the next.
