And again, I've written for you, but you can figure out what the electron configuration is just by writing up in this order here.
同样，我已经写出来了，但你们可以把这个写出来,就知道电子轨道构型是什么。
-
Could you tell us what process you went through in order to get here?
你能告诉我们你到这里经历了哪些过程吗？
-
So the correct answer for titanium plus two Ar3d2 is going to be argon 3 d 2, whereas if we did not rearrange our order here 4s2 we might have been tempted to write as 4 s 2 so keep that in mind when you're doing the positive ions of corresponding atoms.
所以正2价钛离子,的正确答案是，然而如果我们不重新安排顺序,我们可能会写出2,所以请记住,它当你们在解关于原子,的正离子的时候。

Here, this destruction brings forth a new order, a new form of life that Yeats calls "terrible beauty."
这时，毁灭带来了新秩序，带来了新生活,叶芝称之为，惊人之美“

So in fact, what does that suggest about the order of growth here? What is the complexity of this? Yeah. Logarithmic. Why?
复杂度是多少？,对的，对数级的么？，为什么呢？,学生：对数级的？
-
OK, but in order to relate turning these physical knob to this quantity here, which we don't have a very good feel for, we've got to have a feel for the slopes.
热量是怎么进一步改变的,但是为了把这些物量同我们，不是很理解的焓联系起来，我们对微分已经有了一定的了解。

So here it is, I've got my first order condition.
到这里我满足了一阶条件

Milton explains that the Licensing Order of 1643 is ineffective, it's useless because, and I'm quoting here, " order avails nothing to the suppressing of scandalous, seditious, and libellous books, which were mainly intended to be suppressed."
弥尔顿解释说《出版管制法》毫无作用，一无是处，我引用他的话说原因“,因为这个管制法对控制诽谤性的，有煽动性的，中伤他人的需要被控制的书籍毫无用处“

So let's figure out the bond order for our two molecules here that we figured out the electron configuration for.
让我们看看这里,两个分子的键序是多少。
-
You got an extra hint here in terms of the order, so even if you had just forgotten what I said, sometimes it's not a terrible idea just to put it in the order it's written, that can give you a lot of clues as well.
其实大家还可以发现一个额外的提示，因此即使你忘了我刚才说的，有时候直接按照这个顺序,排列也不失为一个办法，这也可以给你很多提示。
-
I'll let you chase it through, it does work. What I want to look at is, what's the order of growth here?
我会让你们去运行这个方法的，确实能得到正确答案，我想问的是，这个解决问题的方法的增长率是什么？
-
Generally, we ignore the high order terms here.
这样，当我们在工程上。
-
But what I really want to talk about is, what's the order of growth here?
但是我这里真正想讲的是，这个问题的增长率是多少？
-
OK. Order of growth here.
好，让我们来想想。
-
If, in fact, a gold nucleus was this size here, we would need to use another lecture hall in order to find a place to put this nucleus right here.
那么这个实验就太诡异了，所以我们决定,把距离压缩一下，我们要考虑到这一点。
-
OK. Now I want to know what's the order of growth here?
那我想知道,这个解决方法的增长率是多少呢？
-
What do you think the order of growth is here?
这儿有一个数组？
-
Now. What's the order of growth here?
这里的增长率是多少，复杂度呢？
-
What's the order complexity here?
这个复杂度是多少？二次？

So, summarizing better, assert is something you put in to say to the user, make sure you're giving me input of this type, but I'm going to guarantee you the rest of the code works correctly. Exceptions and exception handlers are saying, here are the odd cases that I might see and here's what I'd like to do in those cases in order to try and be able to deal with them.
所以更好的总结下,断言就是你放在那里告诉用户,保证你输入的是这种类型的,但我能保证剩下的代码运行正确,异常和异常处理做的事,这里有些我能预期的异常情况,并且这里有些情况,我能尝试处理。
-
Remember, because that 1 s orbital is all the way down in terms of if we're thinking about an energy diagram, we're all the way down here, so we have a huge amount of energy we have to put into the system in order to eject an electron.
还记得吧，因为1，s，轨道在能量示意图里,是在最底部的，我们要一直到最下面，所以我们要向这个系统注入非常大的能量,才能打出一个电子。
-
OK. What would you guess the order of growth here is? Yeah. Why? Good. Exactly. Right?
如果没听到答案的同学,答案是对数级的？
-
Right. Order of growth here.
你们是怎么想的？
-
The order complexity here, if I actually write it would be-- sorry, order n times m, and if m was equal to n, that would be order n squared, and this is quadratic.
如果m等于n的话,也就是n的平方，这是一个平方复杂度的问题，这是和前面不同类型的，好，我在做什么呢？
