It's much more relevant to set our zero point energy as the separation of a bond in terms of talking about the reactions that we'll usually be dealing with here.

更好的是把零点能定在,键断裂的时刻,在讨论化学反应的时候,而我们以后将经常遇到化学反应。

The yield-to-maturity on an indexed bond is already in real terms because the coupons are indexed to inflation.

这种债券的到期收益率,就是实际收益率,因为票息已经被通胀指数化了

/2 So this would mean the bond order is equal to 1/2, and in terms of valence electrons, how many bonding valence electrons do we have?

这意味着键序等于，对于价电子，有多少个成键价电子？

So the point is, this balance between energy thatyou could think of as say bond energies in chemical reactions, and entropy that you can think of in terms of disorder, how many different possible combinations or configurations of something wrong, will dictate where the equilibrium lies.

关键在于，这种能量与熵之间的平衡,确定了平衡的条件，在化学中能量涉及键能，而熵和无序有关,即有多少可能的不同组合或者形位，二者的平衡会告诉我们平衡态是什么样子。

That's the huge force that we're talking about in terms of making a bond stable, but there are also repulsive forces, so you can imagine we're going to have electron-electron repulsion between the two electrons if we're bringing them closer together.

正是这个非常强的力,使得我们所讨论的这个键能够稳定存在，但是其中还有排斥力存在，大家可以想象一下,我们会有电子与电子之间的排斥力,如果让它们离得更近。

So in terms of naming our o h bond, good, it's right here.

对于OH键的命名，很好，在这里。
