When the metal coating is punctured or scratched, the capsules in the damaged area burst and ooze restorative liquids, in the form of compounds called trivalent chromates.

当金属的覆盖层受到扎刺时，受区域的胶囊将会破裂并渗出具有恢复性的液体---三价铬钝化化合物。

Their electrons form an extremely strong triple bond with each other, which, in nature can usually only be broken by a molecule being hit by lightning.

它们的子形成了一个极强的三价键，在自然界，通常只有在分子被闪时才会被破坏。

It has 14 nitrogen atoms and because of the way the molecule was structured, none of them are in a triple bond.
