玻璃杯半满。
玻璃杯是半满的还是半空的呢?
而你还认为瓶子是半满的。
So that's what we are going to focus on, and you will find out that the laws of physics for this entire semester certainly can be written on one of those blackboards or even half of those blackboards.
这就是我们的课程重点,而且你将来会发现,整个学期的全部物理定律,最多也只能写满一块黑板,或者半块黑板
So, our two glitches we see when we go from the 2 p, or from 2 s to start filling the 2 p, and then we also get another glitch when we've half-filled the 2 p, and now we're adding and having to double up in one of those p orbitals.
因此,我们的看到的两个小偏差,一个是在开始进入,2,p,轨道,或者说在填满,2,s,轨道之后,开始填,2,p,轨道的时候出现的,另一个则是在,2,p,轨道半满之后,开始继续加电子,使得其中一个,p,轨道上的。
So if we're comparing the difference between these 2 now, what you'll notice is that in nitrogen we have all half-filled 2 p orbitals, and now, once we move into oxygen, we actually have to add 1 more electron into 1 of the 2 p orbitals.
那么如果我们来比较下它们两个有什么不同,你会发现氮的,2,p,轨道,都是半满的,现在,我们继续看一下氧,我们不得不在其中一个,2,p,轨道上,再放上一个电子。
