double bond
常见例句
- 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。 - Electrons can cause this double bond to rotate, which places part of the wheel in close proximity to a bulky side-molecule attached to the hub.
电子可以使这个双拼接口旋转,使得轮子的一部分紧靠连接轮毂的一个大型从属分子上。 - 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。

而且我们发现这两个原子的情况是一样的,它其实不是一个双键,而是介于单键与双键之间的。
