We can know this information even if we just knew that the bond was stronger, we wouldn't need to look at a graph here, because it turns out that if you have a stronger bond, -- that also means that you have a shorter bond -- those two are correlated.

我们依然可以得到上面的信息,即使我们所知道仅仅是这个键更强，我们不需要去看这个图，因为事实上如果你有一个更强的键，这也就意味着你有一个更短的键-,这两点是互相关联的。

You wouldn't buy this bond at par because at par, meaning at $100- because then you wouldn't get any interest on it.

你不是以平价买入,平价买入,意思是以100面值买,否则就没有利息收益了

The Corinthians are free; they will be violating no law or sacred bond if they say, sorry we really don't feel like doing that.

科林斯人可以自由选择,帮还是不帮,如果他们说对不起,我们不想帮忙,他们没有违反任何法律或某种神圣约束

Alternatively, if I went back to the office and took Yale's $22.5 billion dollars and decided that I was going to day trade bond futures, security selection wouldn't have anything to say about the returns; asset allocation wouldn't have anything to say about the returns.

或者,如果我回到办公室,把耶鲁的225亿美元,投资于即日平仓的债券期货,在这种情况下,证券选择不会影响回报率,资产配置也不会影响回报率

So again, we can name these molecular orbitals and these we're going to call also to point out there is now a bond axis along this nodal plane, which is something we didn't see before when we were combining the s orbitals.

同样的，我们可以,命名这些分子轨道,这些轨道叫做-同样要指出的是,现在沿着键轴是一个节点面，这是我们讨论s轨道的时候,从没有看到过的。

So what I want to point out with this case in beryllium is that you don't have to use all of the electrons to figure out the bond order, and in fact, once you get to molecules 10 that are from atoms with atomic numbers of 8 or 10, you're not going to want to maybe draw out the full molecular orbital diagram.

我要指出的是,在Be这种情况下,你不需要利用,所有的电子来指导键序，实际上，一旦分子中,原子序数到达了8或者，你也许不想画出,整个分子轨道图。

So what actually turns out the reality is that h e 2 does exist, but it exists as the weakest chemical bond known, and it wasn't, in fact, even found to exist until 1993, so I can assure you this is not a bond that you see very often in nature, and it is a very, very weak bond.

实际上He2键是存在的，但它是目前所知的最弱的键，直到1993年它才被发现，所以我可以向你们保证在,自然界你们不可能经常看到它，它是种非常非常弱得键。
