Or if we look at how strong it is, it's actually stronger than a single bond, but weaker than a double bond.
或者如果我们看键的强度的话，它实际上比单键更强，而比双键更弱。
So really, you can not ever rotate a double bond, it makes your molecule very rigid.
实际上，你不能转动一个双键，它使得你的分子很坚固。
So if we look at its length, it's actually shorter than a single bond, but longer than a double bond.
因此如果我们看它的键长的话，它实际上比单键更短，却比双键更长。
