我们来考虑一下如何划分单键、双键和三键。

Let's think about how we can classify single and double and triple bonds,.

“一锅”法的碳-碳双键形成反应。

"One - pot" carbon - carbon double bond formation.

烯烃的双键：重点是反应活性。

The Alkene Double Bond: a Focus of Reactivity.

环外的双键的张力效应导致相反的结果。

With exocylic double bonds the effect of strain is in the opposite direction .

与二烯烃橡胶相比，EPDM的双键很少。

Compared with diolefine rubber, EPDM has less double bond.

所以双键把它们锁定在某一特定形状，是十分重要的。

So it's very important that the double bond locks it in a particular conformation.
