So we know every time we have two electrons, that's a bond.
我们知道每当我们有两个电子，这就是一个键。
Finally, I just want to say that we have also a kind of bond called an indexed bond, which is a bond whose coupons are indexed to inflation.
最后一点是，一种叫物价指数债券的债券，这种债券的票息被通胀指数化了。
So it already should make sense why we have that p orbital there, in order to form a pi bond, we're going to need a p orbital.
这里有p轨道是很合理的,为什么我们在这里有P轨道，为了形成一个π键，我们需要一个p轨道。
sigma2sp It's going to be a sigma bond. So, we have sigma 2 s p, carbon 2 s p. So they're two s p bonds combining.
是sigma键，我们有，碳2sp。，所以它们是两个sp键结合。
But in sigma orbitals, you have no nodal planes along the bond axis, so if we had a nodal plane here, we'd see an area where the wave function was equal to zero.
但在sigma轨道里，沿着轴向是没有节点平面的，如果我们有个节点，我们就会看到某个地方波函数等于0。
So we have h, then we can draw our bond as a line.
那么我们有氢，可以把我们的键画成一条线。
Remember, every time we have two electrons that are being Shared, that's a single bond.
还记得，每次我们有两个电子被共用，我们就有了一个单键。
When such kindness is offered, we are finallyable to see the worth of those we have previously written off, andbefore weve known it, a bond has formed, regardless of whetherothers can understand it.
当这样的帮助提供给我们的时候，我们才明白曾经失败的价值。 在我们相识之前，一条纽带就已经把我们连接在一起了，不管别人能否理解。
When we have just a single bond in them molecule, you have all the free rotation you want, you can just spin it around, there's nothing keeping it in place.
当我们在分子力只有一个单键时，你可以随意旋转，你可以让它转起来，没有什么东西能固定住它。
It's a fair question, considering the market turmoil we have experienced, and many market participants - investors, bond issuers and regulators - have asked it.
考虑到我们刚刚经历过的市场动荡，而且许多市场参与者(投资者、债券发行者与监管者)都曾经问过这个问题，我不得不说这是个合情合理的问题。
What we're going to do in forming a molecule is just bring these two orbitals close together such that now we have their nucleus, the two nuclei, at a distance apart that's equal to the bond length.
我们在形成一个分子时要做的就是，把这两个轨道放到一起，这样我们有他们的原子核，两个原子核，它们之间的距离为键长。
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。
This would mean that we did not have to be as close with the rest of the wider group - as long as we had a strong bond with around 5 others.
这意味着只要我们和5个朋友关系亲密，就无需与更多的人保持紧密联系。
When such kindness is offered we are finally able to see the worth of those we have previously written off and before we've known it a bond has formed regardless of whether others can understand it.
当这样的帮助提供给我们的时候，我们才明白那些曾经认为不可救药的人的价值。在我们发现之前，一条纽带就已经把我们连接在一起了，不管别人能否理解。
And then we have a triple bond there because we have 3 pairs of electrons.
然后那里还有一个三键，因为我们有三对电子。
So much so that Buffon is willing to admit: "We have such a strong bond that if he were to make me an offer from any club, I would be very tempted to rejoin him."
里皮有如此多的优点以至于布冯很愿意承认：“我和他有着如此棒的关系，所以如果他希望我和他一起去为任何一个球队效力，我都会非常乐意的加入他。”
