I could take and draw a line continually down the molecule where my finger was touching; my finger would be touching a phosphate here, the 5' carbon, the 4' carbon, the 3' carbon, and the next phosphate.
我可以画一条这样的线,沿着这个分子不断向下延伸到我指的地方,我指的这一点代表着磷酸基,5' 碳部位,4'碳部位,3' 碳以及下一个磷酸基
if we think about electronegativity as a periodic trend we can just draw our nice periodic table here, and let's separate it into quadrants.
如果我们来思考一下电负性的周期性规律,我们可以把我们漂亮的周期表画在这,然后把它分成四个象限。
So I tried to give you one that you could draw pretty quickly, it just has hydrogens in It.
我试着快速的画出这个结构,这是氢原子。
It might not have any electrons in it, but it still exists, so you need to draw these into your molecular orbital diagram.
也许它里面没有电子,但它是存在的,所以你需要在分子轨道图里画出来。
So, let's go ahead and make sure we can draw that, if we have interest either in the area of organic chemistry or biochemistry or biology here.
那么,让我们来确认一下我们已经学会怎么画了,如果我们对有机化学,生物化学或者生物学中的任何一个领域感兴趣的话。
So, how do we figure out first how to draw the skeletal structure of this molecule here?
那么,我们如何来解决它,首先是如何画出这个分子的骨架结构?
And, I know I need to come up with four symmetric equi-length bonds, and let's just see, let's draw the structure here.
我想我们需要,4个对称的等长的键,让我们画出CH4的结构。
And so, if we go and we draw this again, if this is the carbon here, hydrogen, hydrogen, hydrogen, hydrogen like this, then this is going to be a little bit plus.
如果我们继续,我们将再次画下这个,如果这儿是碳,氢,氢,氢,氢,就像这样,这里有些正电荷。
So this means we can actually calculate this for any molecule that we've drawn the Lewis structure for, because we actually do need to draw the Lewis structure before we know, for example, how many of each of these we have, or at least go through the rules.
这意味着我们可以将原来画过,路易斯结构的分子的形式电荷计算出来,因为我们其实在画出,路易斯结构之后才能知道,比如,这些量的值是多少,或者至少我们需要经过前面的那些步骤。
Okay, so the rule for adding the two vectors is, you draw the first one and at the end of that first one, you begin the second one.
矢量的加法法则就是,先画出第一个矢量,然后在它的终点,再画第二个矢量
And resonance is the idea that sometimes one single Lewis structure does not adequately describe the electron configuration around a given molecule, so instead you need to draw two different Lewis structures to describe that more appropriately.
而所谓共振态,就是有时候一个路易斯结构不足以,完整描述一个给定分子的电子排布,因此这时你需要同时画出两个,不同的路易斯结构来描述它,这样会更恰当。
We may be in a recession now; a lot of people are saying that, so I would be tempted to draw a new line here, somewhere around here, maybe December of 2007.
也许现在正在经历衰退,人们普遍这样认为,所以我想在这画条新的直线,画在这附近,也许是2007年12月
Let's draw a little picture on the side here.
我们在边上简单地画个图来看看吧
Try and draw it better in your notes.
你们在笔记本上好好画一下吧
Can you draw the vector for me?"
你们可以画出这个矢量吗"
People do draw other forces.
真的有人乱画其它力
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。
Well, it was not very hard for me to draw this red blood cell here, it's just an oval, and one reason I draw it like an oval, is that that's basically what it looks like if you look at it.
我可以很容易的画出,一个血红细胞,就画个椭圆足矣,因为它看上去就是这个样子的
Once you're doing this on your own, -- especially, for example, on exam 2, which is a ways down the road, you won't be able to look at those steps, so you need to make sure that you can go through them without looking at them, but for now we can look at them as we are actually learning how to draw the Lewis structures, and rather just go through them step-by-step, it's more interesting to do it with an example.
每当你要画一个路易斯结构的时候,特别是,比如,在第二次考试中,在不远的将来,你将看不到这张表,因此你需要确保自己在不看这张表,的情况下也能按照上面的流程来画,但是目前我们是可以看着这张表,来学习如何画路易斯结构的,而相比于一步一步地讲,通过例子来演示一下会更有意思。
