OK, so do we know anything so far that we can point to that would give us a departure?
好，到目前为止我们能在我们了解到的,东西中找出一些违背这些规律的例子吗？
-
So, in this case, we're just drawing the molecular orbital diagram for the valence electrons, so we have three for each.
所以在这个例子里面，我们只需要画出,价电子的分子轨道图，所以每个有3个电子。
-
The take-away for now is really to look back at some of the examples we've seen in lecture, some of the examples that you've now seen in the super sections and in the future sections really, for guidance.
抛开那个，我们回头看看,我们在演讲中看到的例子，其中一些,你们在超级课程中看到的例子,在以后的课程中，作为指导。
-
And I'll also remind you, and we're going to see this in the next example, we talked about looking at the worst case behavior. In these cases there's no best case worst case, it's just doing one computation.
我还要提醒大家的就是，我们也会在下一个例子里发现者一点，我们谈到了要去考虑最坏的情况,在下面这些例子里,没有好情况坏情况之分，就只是一次运算。
-
Is that, in that comparison, is that a way we can judge what is a good poem?
在您的例子中，这也是我们评价一首好诗方法么？
-
Well,instead of pursuing that example,let me give you a slightly different example that's been discussed a fair bit in the philosophical literature.
这次让我们换个不太一样的例子,这个例子在哲学文献中经常被讨论。
-
This is an example where the external pressure here is kept fixed as the volume changes, but it doesn't have to be kept fixed.
在我们举的这个例子中,外界压强不变，气体体积改变。
-
Finally, in the examples we're giving, whenever the pig does something you like you reinforce it.
最后，在我们之前提到的例子里，每当那头猪做出让你满意的行为,你就会强化它。
-
We'll come back to this in our example in the cardiovascular system when we're talking about the heart and we'll talk about how to measure the collective group of action potentials using EKG's.
这个我们回头再谈,等到我们在心血管系统的例子中,说到心脏时再说,我们会谈到如何通过,心电图测量群体动作电位
-
So I just wanted to give another example a little closer to home in the poem of Yeats, the 1935 poem "Lapis Lazuli."
再举一个,更贴近我们的例子,1935年，Yeats在“Lapis，Lazuli“一诗中写道“
-
So, similarly in a case where instead we have a small energy difference, we're going to have a low frequency, which means that we're going to have a long wavelength here.
在这个例子里,能量差较小,我们得到的频率低,这意味这它的波长更长。
-
PROFESSOR: And so in this case, it's using the same piece, but it's returning that middle value that says they're actually the same.
教授：那么实际在这个例子中，我们用的是同一个函数，它返回了中间的值也就是,0来表明着两个参数。
-
So let's go to some actual real examples, which might come more in handy for this class.
下面让我们来看一些正确应用它的例子，这些例子在这个课堂上应该更容易一些。
-
And of course,we know that there are many, many other cases in which people die in the presence of their friends, family,loved ones.
当然我们知道有很多，人们在亲朋好友面前，死去的例子。
-
Then at the end, we'll look at an example with a heteronuclear diatomic molecules.
在最后，我们会看一个,异核双原子分子的例子。
-
And we saw a couple of examples of linear algorithms.
这是线性算法的典型例子,我们在过去也看过了大量的线性算法的例子。
-
So this first little piece of code right here says, ok you give me 2 points, I'll create another 1 of these lists and I'll simply take the x, sorry I shouldn't say x, I'm going to assume it's the x, the x-values are the two points, add them together, just right there, the y-values, add them together and return that list.
好，为了来认识到这一点,让我们来看一个简单的小例子，在你们的课堂手册上，你可以看到我写了一个小程序,它假设我得到了，这些点中的一些，我想对它们做一些操作，例如我想把它们加到一起，那么这里的第一小片，代码的意思是，好给我两个点，我会再创建一个数组。
-
So if we have total +2 and complete shielding -1 where that can actually negate a full positive charge, because remember our nucleus is plus 2, +1 one of the electrons is minus 1, so if it totally blocks it, all we would have left from the nucleus is an effective charge of plus 1.
抵消一个完全的正电荷,因为记住我们的原子核是,其中一个电子是,所以如果它完全挡住了它，我们从原子核中留下的，全部有效电荷就是，所以，在我们的第一个例子中,我们的第一种极端情况。
-
Second thing they're going to do is let us suppress detail. And in essence what that does is, the functions, and we're going to look at a bunch of examples in a second, these functions are going to give us a way to, in some or in one way of thinking about it is to create new primitives.
第二件要做的事,是忽略细节,函数的本质到底是什么,我们将在接下来的几分钟，举一些例子，这些函数将给我们提供,一种创建原语的思考方式。
-
I want you to look at this picture, read the little bit about gene - control of gene expression - that's in the book, know that it's a big topic, that we're not going to talk about it except we're going to talk about some examples where control of gene expression can be exploited in order to treat diseases, for example. So I'll see you on Thursday.
所以我希望你能看一下这张图,读一些,教材里基因调控的章节,这是个很大的话题,我们不会进一步深入去探讨,但一些基因调控,用以治疗疾病的例子,我们可能还会在之后的课程中讲到,那我们周四见了
-
In Philip's case, we ask the question, does he have zero or none zero socks on his feet?
在飞利浦这个例子中，我们就需要判断，他的脚上有没有袜子？
-
And you might every once in a while get this, at least as we've done it in this case, this large move out at the end.
一旦你得到了这个结果，至少像是我们在这个例子中得到的结果，最后有一个很大的唯一变化。
-
All right. What does this have to do with my divisor example? This says I can make tuples, but imagine now going back to my divisor example and I want to gather up the elements as I go along. I ought to be able to do that by in fact just adding the pieces in.
这意味着我可以创建元组了,但是想像下回到我们的除数的例子,在处理过程中我们想把目标数的除数,收集起来，我应该能够通过把这些数,一个一个加进来来实现这个目的,我正是要去这么做，也就是。
-
There's no underlying David Smith personality still there, to have the counterexample or the example that we're after.
那里面没有潜在的David，Smith人格，来成为人格理论的反例或我们在寻找的例子。
-
And if we talk about chlorine, and both of the chlorines are the same in this case, we start with a valence number of 7 for chlorine, and then we subtract 6, because it had 6 lone pair electrons around each of the chlorine atoms.
而如果我们讨论氯的话，在这个例子中两个氯的情况都是一样的，从七个价电子开始，然后减去六，因为每个氯原子周围,都有六个孤对电子。
-
And then on the right hand side I++, we saw that in pseudocode with our socks example last week that just says increment I.
然后是最右边的i++，我们上周在socks例子的伪代码中,曾经见到过，不是么？只是代表i加1而已。
-
So in this first case here, what we're seeing is a sigma bond.
在第一个例子里，我们看到的是sigma键。
-
I can write it explicitly. I can write it inside of a FOR loop. And we've started to add, and we'll see a lot more of this, examples of collections of structures so that we don't just have to do something that can be easily described as walking through a set of things but can actually be a collection that you walk through.
我可以明确的写出来,我可以把它在FOR循环的内部写出来，然后我们开始学习了add这个运算符,我们会在以后学习很多的,集合的数据结构的例子,这样一来我们可以进行一些,很简单的遍历集合的操作,我想要为大家指出的最后一件事情是。
