石墨

If you talking about the high boiling point of graphite, this is due to the strong covalent bond between each carbon atom.

如果你是指石墨的高沸点，这是因为碳原子之间强大的共价力所形成。

For boiling, all the covalent bond between the carbon atom have to be broken, therefore, it requires high temperture to provide large amount of energy to it.

要使石墨达到沸腾，必须要将所有的共价都打碎。所以，需要很高的温度还有能量。
