But imagine I actually wanted to gather them together. I wanted to collect them, so I could do something with them.
把那些除数都显示出来,这很有用,但是请想想下我想要,把它们放在一块。
I don't know where you would keep them.
我想不明白你要把它们放在哪儿。
I have shown that by taking Avogadro's number of individual ion pairs and putting them all together in a line, the system's energy became more negative.
我推导出了,从每一个离子对中抽出阿伏加德罗常数,再把它们放在一起在一列中,这个系统的能量就变得更负。
This is very easy molecule because we know exactly where to put them without even having to think, we only have one option, and we'll make a triple bond between the carbon and the nitrogen.
这个分子非常简单,因为我们知道应该把它们放在哪里,甚至不用去想,我们只有一个选择,我们将在碳与氮之间形成一个三键。
I would put them in my room and hang them all over the walls and just look at them and wonder what was happening at this particular intersection or in this area or how to get down this road most efficiently.
我会把它们放在我房间里,挂满整个墙,只是看着它们,想,这个十字路口发生了什么事,或是这个地区,怎样最快走到这条路。
Having drawn all those distinctions, I'm going to just ride roughshod over them and put them aside.
将这些区别都提出来后,我就将把它们放在一旁。
It's to be understood that we have to think of them together.
我们只有把它们放在一起才能理解。
Lay it down and make sure it's in the right position, right?
确保把它们放在合适的位置,我说的对吧?
If I took two double stranded DNA molecules and I exposed them to certain conditions that caused them to denature, that means its native structure falls apart.
假如我把两条DNA双链,放在特定的条件下,使它们变性,变性表示使它们的原始结构分开
Right, so the fundamental idea then, is, I want to glue together information, I want to take pieces of data that naturally belong together, glue them together, and attach some methods to it.
放在一起的数据拿出来,把它们放到一起,然后把一些方法附加上去,这些,你知道的,是很长的一个定义,让我们来看个例子吧。
Versus looking at, for example, helium or neon or argon, these are all inert gases, inert meaning essentially do not react, those were grouped together in the periodic table.
相反,他发现氦,氖,氩,都是惰性气体,惰性的意思是基本不参与化学反应,因此把它们放在周期表中的同一类里。
But having gestured toward them,I want to put them aside.
但已经提过之后,我想把它们放在一边。
We'll just put them in some way around our sulfur atom.
我们只要随便把它们放在硫原子周围就行了。
But since in drawing Lewis structures actually, in some cases you do, you can draw a dotted line that means a 1 and 1/2 bond, but most in most cases, we just draw out both resonance structures, and the way that we say it's a resonance structure is that we put it in the brackets and we put an arrow between it.
但是由于在画路易斯结构时,其实,在某些情况下是可以的,你可以画一条虚线来表示一又二分之一键,但是在多数情况下,我们就把两个结构都画出来,而我们说这是一个共振结构的表示的方法是,把它们放在括号里,并在中间放一个双箭头。
And what we end up forming is a molecular orbital, because as we bring these two atomic orbitals close together, the part between them, that wave function, constructively interferes such that in our molecular orbital, we actually have a lot of wave function in between the two nuclei.
最后我们得到了分子轨道,因为当我们把这两个原子轨道放在一起的时候,它们之间的部分,波函数,相干相加,所以在分子轨道里,我们在两个原子核之间有很多波函数。
So, let's just arbitrarily put it between these two in this case here, but actually there's no reason we couldn't also put it between oxygen b and c, so I'm going to draw another structure where we have it here.
那么,让我们任意地将它们放在这两个之间,但实际上我们没有理由,不能把它们放在氧原子,B,与,C,之间,因此我将把另外一个结构画在这里。
And if you put this in the well-ventilated area, if you prepare this outside, the h c n gas will actually be released into the air, so you're safe, you can eat it later.
而如果你把它们放在通风良好的地方,在室外处理,那么氰化氢气体,将会被释放到空气中,这样你就安全了,过后就可以吃了。
If you put those together, you will get 4.
如果把它们放在一起就会得出。
There's absolutely nothing that tells us which atoms we should put it between, because they're both oxygen-oxygen.
我们没有任何理由把它们,放在其中一对原子中间,因为它们都是氧氧键。
So if we want to put that in chemical terms, we want to make sure we put these in brackets here, and remember, this is the resonance arrow, it's not a reaction arrow, it's a resonance arrow, so make sure you mark it up correctly like that.
那么如果我们把它类比到化学中来,我们要确保它们都放在括号里,而且要记住,这是一个表示共振态的箭头,而不是表示化学反应的,它是一个表示共振态的箭头,因此请务必像这样正确地标记它。
