第六步是想一想我们有多少个成键电子剩下？
Step six is thinking about do we have any bonding electrons left?
价电子成键理论，非常容易理解。
So the idea behind valence bond theory is very easy to understand.
我们从成键中获得。
让我们用价电子成键理论来看一看甲烷。
显然，没成键是最弱的。
And obviously, no bond is the weakest of all is not bonding.
这是当我们有3个成键电子，和一个孤对时这样称它。
That's what we call when we have three bonding atoms and one lone pair.
本质上，它只能允许我们,和两个氢原子成键。
Essentially it would only allow for us to bond to two hydrogen atoms.
我们看到3对成键电子所以这是一个三重键，它确实是多重键。
We see three bonding pairs so this is a triple bond, indeed a multiple bond.
结构和成键。
分析了V - N -空位复合体的成键特性和电荷转移情况。
The bond characteristics and charge transfer in the V-N-vacancy complex are analyzed.
当将数据分解成多个具有外键关系的表时，这尤其重要。
This is important when data is decomposed into multiple tables having foreign key relationship.
