相对于通过键列跨不同的表链接不同行,最佳实践将是在一行中有许多列。

R PG程序更新通过键访问的行之前,必须执行一个读操作,以便锁定该行,进行更新。

So, we know from our calculation that we can do over here, that this bond is polar.
我们通过计算都知道,这个键是非极性的。
I've got two states here, three states here, two here, I need four, and if I can come up with these bonds, four, by the Hund rule I'd fill them like this.
我们已经有2个状态在这里,3个在这里,2个在这里,我需要4个,如果我能想到这些键,四个,通过洪特规则,我们就能像这样排布。
And the reason we can see that by looking at this graph is that we see that nitrogen when it's bonded is in an even lower well than we saw for hydrogen.
原因可以通过观察这幅图发现,我们看到氮在成键之后将处于更低的势阱中,对氢而言。
