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

在超级金刚结构中，这同适用，但是不同是，较普通金刚更耐磨损。

But his body was as hard as a diamond.

但他跟金刚一坚硬。

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。

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钻头改成钻。

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

与墨和金刚一，化学键差异也会导致不同网状结构。

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，而是由许多极小连接在一起金刚晶组成。

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.

墨和金刚这两种碳单质，硅和它氧化物也是网状结构固。

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

小朋友，你见过钻吗？钻，也叫金刚，是一种非常光亮，非常坚硬头，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，但它是一种不同、更耐磨金刚形式。

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有关碳知识，来制造比金刚更坚硬物质。

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

这是金刚网络结构使其与墨完全不同另一种方式。

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

但是， 尽管金刚导电性能很差，但墨和金刚都是良好热导。

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

因此，当一个区域热能增加时， 它会迅速扩散到整个金刚或墨中。

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。

Allotropes of an element can have very different properties from each other (graphite and diamond, for example, are both allotropes of carbon).

一种元素同素异形可能彼此具有非常不同性质(例如，墨和金刚都是碳同素异形)。

The solution was a lubricant that contains diamond-like nano flakes that would not only help prevent wear, but reverse it.

解决方案是一种含有类金刚纳米薄片润滑剂， 它不仅有助于防止磨损， 还能逆转磨损。

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

在金刚中， 每个原子中成键电子排列在 SP3 轨道中。

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

例如，将金刚变成墨反应在热力学上是自发。

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，更酷是，这些是我们所知最坚硬、密度最高，几乎无法压缩材料。
