And that was an exciting thing because no one thought of carbon would come yet in another form after all diamond and graphite have been known for millions of years.

那是个让人兴奋的东西，因为从来没有人想过，在金刚石和石墨被大家熟知的万亿年后，碳其实还有另外一种形态。

A lump of graphite or a diamond will sit happily on a laboratory bench without bursting into flames, or even rusting, and is impervious to the action of water.

一块石墨或是一颗钻石能很悠然自得地躺在实验台上而不会被灼烧成火焰或被锈化，并且由于其不透水性，它是不会和水发生反应的。

It is, though, surprisingly inert. A lump of graphite or a diamond will sit happily on a laboratory bench without bursting into flames, or even rusting, and is impervious to the action of water.

一块石墨或钻石可以放在实验室的长凳上而不会自燃，甚至不会生锈，也不会受到水的影响。

For instance, graphite and diamond are both made of carbon, but the difference in the crystalline arrangements of their carbon atoms means that graphite conducts electricity while diamond is a good insulator.

Their results suggest 55 Cancri e is largely composed of carbon (in the form of graphite and diamond), iron, silicon carbide, and, potentially, silicates.

Elemental carbon had long been thought to exist in only three physical forms: graphite, diamond and an amorphous form, of which charcoal is an example.
