Its molecules form tetrahedral shapes — that's a triangular pyramid, or a d4 if you're into tabletop RPGs.

它的分子结合成体形——这是一种三角形的棱，或者是桌角色扮演游戏中的d4。

On a chemical level, a diamond is just a bunch of carbon atoms bonded together in tetrahedrons.

从化学角度来看，钻石是一堆碳原子紧密结合成的体结构晶体。

The next stage of decay would be, it would be four sides.

下一阶段的衰变将会是体。

Okay, that simple shape like a triangle or maybe a tetrahedron in 3D.

好的，就是那种简单的形状，比如三角形，或者三维空间中的体。

And this is that tetrahedral shape.

这就是那体形状。

And so water is locked into that tetrahedral structure.

The same thing does for CH4 with its tetrahedron of weakly electronegative hydrogens around a more strongly electronegative carbon.

同样的情况也适用于CH4，其弱电负性的氢原子围绕着一较强的电负性碳原子形成了一体结构。

Over 160 kilometers beneath the Earth's surface, the intense heat and pressure forced carbon atoms into that tetrahedral structure to form diamonds.

Curious about the space between the planets, he hypothesized that each gap must correspond to one of the Platonic solids: the tetrahedron, cube, octahedron, icosahedron, and dodecahedron.

出于对行星之间空间的好奇，他假设每间隙都必须对应一柏拉图立体：体、立方体、八体、二十体和十二体。

This in its turn was placed inside an icosahedron, then followed the orbit of Earth, a dodecahedron, Mars, a tetrahedron, Jupiter, a cube, and finally Saturn.

这之后放置在一二十体内，接着是地球的轨道， 一十二体，火星，一体， 木星，一立方体，最后是土星。

Cycloalkenes also start at three carbons and get increasingly stable as more are added, though their double bonds make their molecules plainer instead of tetrahedral.

环烯烃也从三碳原子开始， 并且随着添加更多碳原子而变得越来越稳，尽管它们的双键使它们的分子更简单而不是体。
