So this means nitrogen has low electron affinity, it doesn't actually want to gain an electron.

这意味着氮的电子亲和能很低，它实际上并不愿意得到一个电子。

For some of you that haven't I'll just say that it's a protein, it's 238 amino acids, which means that it's about 1,000, actually more than 1,000 atoms in size, and this protein is fluorescent.

对于那些没听说过的人,我要说它是一种蛋白质，它有238个氨基酸，也就意味着它有约1000个，实际上是超过1000个原子，这种蛋白质是有萤光的。

We don't quite clearly understand exactly what that means and who and exactly when.

实际上我们并不十分清楚这学派意味着什么,学派里的谁写的这些书，什么时候写的。

So, it didn't mean that the English state wasn't efficient in collecting taxes, because they were more efficient than the French were in collecting taxes.

So, our detection devices are a little bit limited here today, we're actually only going to be using our eyes, so that means that we need to stick with the visible range of the electromagnetic spectrum.

我们今天所有的探测仪器十分有限，实际上我们要用我们的眼睛来观测，这意味着我们只能看到,电磁谱中的可见光区间。

So because we're feeling a stronger attractive force from the nucleus, we're actually pulling that electron in closer, which means that the probability squared of where the electron is going to be is actually a smaller radius.

因为我们能感到来自原子核,的更强的吸引力，我们实际上会将电子拉的更近，那意味着电子运动的,概率半径是,事实上是一个更小的半径。

This should make sense to you, because they don't, in fact, want to gain another electron, because that would mean that electron would have to go into a new value of n, a new shell, and that's really going to increase the energy of the system.

这对大家来说应该容易理解，因为它们实际上不想得到另一个电子，因为这意味着这个电子不得不,到一个新的，n，值更大的壳层上去，这将会增加系统的能量。
