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

在超级石的结构中，这同适用，但是不同的是，较普通石更耐磨损。

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

石被广泛应用与工业作业中，例如研磨和抛光，因为石非常坚硬。

But his body was as hard as a diamond.

但他的身体就跟石一坚硬。

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石钻头改成钻石。

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

与石墨和石一，化学键的差异也会导致不同的网状结构。

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，而是由许多极小的连接在一起的石晶体组成。

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、石、铀、石油、铜和铁矿石等资源。

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

就像石墨和石这两种碳单质，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，你见过钻石吗？钻石，也叫石，是一种非常光亮，非常坚硬的石头，价钱还特别贵。

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

在超级石中，这仍然是正确的，但它是一种不同的、更耐磨的石形式。

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

这是石的网络结构使其与石墨完全不同的另一种方式。

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

但是， 尽管石的导电性能很差，但石墨和石都是良好的热导体。

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，来制造比石更坚硬的物质。

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石或石墨中。

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，可以碳结晶成石而不是石墨。

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

聚合石纳米棒，或超级石，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。

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

一种元素的同素异形体可能彼此具有非常不同的性质(例如，石墨和石都是碳的同素异形体)。

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石纳米薄片的润滑剂， 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.

在石中， 每个原子中的成键电子排在 SP3 轨道中。

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

例如，石变成石墨的反应在热力学上是自发的。
