Cyanide is a carbon atom triple bonded to a nitrogen atom.

氰离子（cyanide），是碳原子与氮原子以三键结合（C≡N¯）。

These occur when an atom is either triple bonded to another atom or is double bonded to 2 atoms.

当一个原子与另一个原子形成三键或与 2 个原子形成双键时， 就会发生这种情况。

These occur when an atom is either triple bonded to another atom or is double bonded to 2 atoms. The sp orbital, the one that forms the sigma bonds here, is linear.

当一个原子与另一个原子形成三键或与 2 个原子形成双键时， 就会发生这种情况。在这里形成西格玛键的 sp 轨道是线性的。

The pi bonds prevent the triple bonds from rotating here as well, but triple bonded carbons can only bond to one other atom, so even if it could rotate, nothing would change.

π键也阻止三键在这里旋转，但是三键碳只能与另一个原子键合， 所以即使它可以旋转， 也不会发生任何变化。
