If these bonds were all completely of equal distance apart, whether is was a lone pair or bonding electrons, 5° the angles would be 109 . 5 degrees.
如果不管它是孤对，还是成键，它们等距分开的话，键角是109。
-
I've got two states here, three states here, two here, I need four, and if I can come up with these bonds, four, by the Hund rule I'd fill them like this.
我们已经有2个状态在这里，3个在这里，2个在这里，我需要4个，如果我能想到这些键，四个，通过洪特规则，我们就能像这样排布。
-
Cities go bankrupt and they just can't pay, so you as a buyer of these bonds feel reluctant to invest in them.
如果一市政府破产了,他们将无法支付,因此作为投资人,你可能不想购买它
-
So let's talk about ethane and how we would actually write these bonds.
让我们来讨论乙烷,以及如何写出这些键。
-
What kind of a friendship are these bonds of affection that he says hold the city ? together and that make it a regime?
这些感情关系属于何种友情,能像他所言,能将整座城市团结起来并形塑出一个政体？
-
Well, for one thing, the rating companies who rate these bonds.
嗯，一方面来说，评级公司,为债券评级。
-
You know that these molecules are also linked in another way, by the phosphate bonds that connect the 3 and the 5 carbons of adjacent nucleotides.
这些分子还通过别的方式连接在一起,例如通过相邻核苷酸的3碳位和,5碳位之间的磷酸键相连
-
On the one hand it's clearly good that humans rise above the animals and build cities and wear clothes and pursue the arts of civilization and develop bonds of love and duty and friendship the way that animals do not; these are the things that make humans like the gods in The Epic of Gilgamesh.
一方面，成为人类也未尝不是一件好事,人类优于动物，穿着衣服，用自己的双手建造城市,打造文明的生活方式，而爱和责任,把人类联结起来，这些是动物无法比拟的,在《吉尔伽美什史诗》中，这些特质让人类具有神性。

But, I think there will be great opportunities ahead for you and the ability for Wall Street to again securitize and buy a lot of these companies If you have capital, you'll be able to buy these bonds.
但是，我认为在你们未来的道路上将会有很多的机会,华尔街也将会有能力再次保障,或购买很多这样的公司的,如果你有资金的话，你就可以买这些债券。

-
These are long-term government bonds and I--now these are--since they're long-term, they have some uncertainty and variability to them.

-
So why don't you tell me what the valence bond description would be of these carbon hydrogen bonds?
你们来告诉我,碳氢键的价,电子是怎样的？
-
All right, what if I were able to mix these orbitals and produce what he called hybrid bonds?
如果我可以将这些轨道混合起来,成杂化轨道会怎么样呢？
-
So we can have four total hydrogens bonding here, - and we can think about how to describe these carbon- carbon bonds.
我们这里一共有四个氢原子成键，我们可以考虑怎么来-,描述碳碳键。
-
So in addition to having these two carbon bonds, we actually also have four carbon hydrogen bonds in addition to our carbon-carbon bonds.
在这碳碳之间的键以外，我们还有四个碳氢键,除了我们的碳碳键外。
-
So if you think about any one of these carbon-carbon bonds, what type of a bond would you expect that to be?
如果你们考虑任何一个碳碳键，它是什么类型的？
-
Yup, we also have six of these, because we have six carbon hydrogen bonds.
嗯，6个，因为我们有6个碳氢键。
-
It is showing since the U.S. Government issues these bonds, it's showing its data on these bonds.
这里显示了,因为这些债券是美国政府发行的,所以这里显示了这些债券发行的数据
-
Remember, we didn't hybridize the 2 p y orbital, so that's what we have left over to form these pi bonds.
记住，我们并没有杂化2py轨道，这是我们剩下的那个行成了π键。
-
So, what we end up having is three of these pi -- 2 p y 2 p y bonds, we can have one between these two carbons here.
我们剩下的有三个π键-,2py2py键，在这两个碳原子之间会有一个。
-
So, if we think about what bonds are in this molecule, sp2 we actually have six of these sigma carbon s p 2, carbon s p 2 bonds.
如果我们考虑这个分子里都有什么键，我们有六个sigma碳，碳sp2键。
-
So let's think about how we can classify single and double and triple bonds, which is what we're really used to dealing with in terms of these sigma bonds and these pi bonds.
让我们想想怎么来分类单键双键,和三键，这在我们在考虑sigma键,和π键是很有用的。
-
That tells you something about the physical chemistry of the molecule; that it's these hydrogen bonds that hold the double strands and I can break those down under certain conditions.
我们从中可以知道一些,DNA分子的理化特点,双链是由氢键连接在一起,在一定条件下这些氢键可以断裂
-
They also have government-issued notes and that's from one to ten years and bonds this is just jargon- these are ten or more, well actually more than ten.
