Diamonds are frequently used for industrial jobs like grinding and polishing, because they're so tough.

金刚被广泛应用与工业作业中，例如研磨和抛光，因为金刚非常坚硬。

But his body was as hard as a diamond.

但他的身体就跟金刚一坚硬。

Oh, no, not at all. No, we, uh, found a place online that, uh, repurposes diamond drill bits.

不，一点都不贵。我们在网上找到一家店能将金刚头改成。

And also like graphite and diamond, the different forms that they take are all about bonding differences.

与墨和金刚一，化学键的差异也会导致不同的网状结构。

In hyperdiamonds, that's still true, but it's a different, more wear-resistant form of diamond.

在超级金刚的结构中，这同适用，但是不同的是，较普通金刚更耐磨损。

The island is believed to be rich in resources like gold, diamonds, uranium, oil, lead and iron ore.

据悉，格陵兰岛富含黄金、金刚、铀、油、铜和铁矿等资源。

Like graphite and diamond, the two forms of pure carbon, silicons and it's oxides are network solids.

就像墨和金刚这两种碳单质，硅和它的氧化物也是网状结构的固体。

Have you ever seen a diamond? It is a very bright, hard kind of stone, and very dear.

小朋友，你见过？，也叫金刚，是一种非常光亮，非常坚硬的头，价钱还特别贵。

In hyperdiamonds, that’s still true, but it’s a different, more wear-resistant form of diamond.

在超级金刚中，这仍然是正确的，但它是一种不同的、更耐磨的金刚形式。

But we can use what we know about carbon to make a material even harder than diamonds.

但我们可以利用所掌握的有关碳的知识，来制造比金刚更坚硬的物质。

This material is made up of many tiny, interlocked diamond crystals rather than one single structure.

这种材料不是由单一结构构成，而是由许多极小的连接在一起的金刚晶体组成。

Say, I have adiamond for him, too.

说, 我也有他的金刚。

The reaction to change a diamond into graphite, for example, would be thermodynamically spontaneous.

例如，将金刚变成墨的反应在热力学上是自发的。

But even though diamond is terrible at conducting electricity, both graphite and diamond are good conductors of heat.

但是， 尽管金刚的导电性能很差，但墨和金刚都是良好的热导体。

In diamond, the bonding electrons in each atom are arranged in SP3 orbitals.

在金刚中， 每个原子中的成键电子排列在 SP3 轨道中。

Aggregated diamond nanorods, or hyperdiamonds, if you wanna sound cool, these are the hardest, most dense, and least compressible material we know of.

聚合金刚纳米棒，或超级金刚，更酷的是，这些是我们所知的最坚硬、密度最高，几乎无法压缩的材料。

Way down there, the pressure and heat is just right to crystallize carbon into diamond instead of graphite.

在那里， 压力和热量恰到好处，可以将碳结晶成金刚而不是墨。

And here's another way that the diamond's network structure makes it totally different from graphite.

这是金刚的网络结构使其与墨完全不同的另一种方式。

Now, we often find nano-diamonds in meteorites, pieces of rock or metal that fall to Earth from space.

现在，我们经常在陨、从太空坠落到地球的岩或金属碎片中发现纳米金刚。

So when thermal energy increases in one region, it spreads quickly throughout the diamond or graphite.

因此，当一个区域的热能增加时， 它会迅速扩散到整个金刚或墨中。
