"We're looking for concrete steps. And we take it as a positive sign that they've agreed in principle to take a couple of significant steps the opening of the Qom facility, and then working out a procedure for having their low-enriched uranium re-processed in another country.

Anything that's built up out of parts, you could at least in principle worry about the parts coming apart and hence the thing being destroyed.
任何由部分组成的东西,至少原则上讲你都可以担心,这个东西会四分五裂，走向毁灭。

There's a very important principle that finally comes out here, it is that you always want to reduce the variance of your portfolio as much as you can.
现在这里有一个非常重要的原则，即你总是想要降低你投资组合的方差,降得越低越好。

And it works on the principle of trying to figure out how to make your way through the world, how to satisfy your pleasures or, in some cases, how to give up on them.
它试图在现实中找到,满足本我要求的方法，找到追求快乐的方法,有时是去找寻放弃的方法。

In principle, we could play this with the whole class, but let's single out a particular row of the class so I'm going to come down here and I guess eventually, well I'll grab it in a minute.
理论上,我们可以全班一起做这个博弈,但我要选出特定的一行,我先走下来,我觉得,我很快就能挑到人

Pauli So, here, Pauli came out on top, we say, and he's known for the Pauli exclusion principle, which tells us that no two electrons in the same atom can have the same four quantum numbers.
在这里是，他因为Pauli不相容原理而出名，这个原理是说同一个原子中的两个电子,不能有相同的第四量子数。

And when we make these comparisons, one thing I want to point out is that we need to keep the constant principle quantum number constant, so we're talking about a certain state, so we could talk about the n equals 2 state, or the n equals 3 state.
当我们做这些比较时，我想指出的一件事是,我们需要保持常量原则,保持量子数是常数，所以我们在讨论一个确定的态时，我们可以谈论n等于2的态，或者n等于3的态。
-
And we can generalize to figure out, based on any principle quantum number n, how many orbitals we have of the same energy, n and what we can say is that for any shell n, there are n squared degenerate orbitals.
我们可以总结出来，在，主量子数为n的情况下，同一个能量上，有多少个轨道，我们可以说，对任何壳层，有n平方个简并轨道。
