He explained that sometimes during the shock of impact graphite can create jumbled "amorphous" zones that can resist diamonds, at least those coming at them from one direction.

他解释说，对岩石内石墨的冲击能制造出混乱的“无序”区，这种区域可以抵抗钻石的破坏，至少从一个方向上钻石无法穿透它。

The apparent rate of transition reaction from amorphous carbon to graphite is a constant and the reaction order is quasi-zero.

由无定形碳向石墨转变的反应为准零级，其表观速度为常数。

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.
