So, if I kind of circle where the probability gets somewhat substantial here, you can see we're much closer to the nucleus at the s orbital than we are for the p, then when we are for the d.

我把概率,很大的地方圈出来，你们可以看到在ｓ轨道上,比ｐ轨道更接近原子核，最远是ｄ轨道。

What we do care about is the energy of our orbitals that have electrons in them, and if we combined all four of the orbitals, then our hybrid orbitals would have more p character to them, so they'd actually be higher in energy.

是不是很高,我们不关心它的能量很高，我们关心的是，有电子的轨道的能量，如果我们把四个轨道结合。

There are scholars of all stripes and allegiances who view P as late; and there is some very good objective evidence for dating parts of P to the post-exilic period, just as there is good objective evidence for dating parts of D and the other sources to the post-exilic period.

有各种不同见解的学者认为P资源出现较晚;,而且还有一些有力的客观证据,来确认P资源来自流放后时期，也有有力的客观资料确认D来源的时间考证,也有其他的资料来源于流放后时期。

So if we compare l increasing here, so a 3 s to a 3 p to a 3 d, what we find is that it's only in the s orbital that we have a significant probability of actually getting very close to the nucleus.

我们比较当ｌ变大的时候，从３ｓ到３ｐ到３ｄ,我们可以发现只有ｓ轨道,有很大的概率,非常接近原子核。

That's it. Again, these other p dxy dyz - or the d x y, d y z, those are going to be those more complicated linear combinations, you don't need to worry about them.

同样，这些p轨道,或者，它们是一些,很复杂的线性组合，你们，不用管它。

So, it's very easy to calculate, however, the number of radial nodes, and this works not just for s orbitals, but also for p orbitals, or d orbitals, or whatever kind of work of orbitals you want to discuss.

径向节点，的数量，这不仅对s轨道适用，对p轨道，d轨道，或者任何你们想讨论的轨道，都是适用的,它就等于。

So again, what we see is the same pattern where the most probable radius, if we talk about it in terms of the d, that's going to be smaller then for the p, and the 3 p most probable radius is going to be closer to the nucleus than it is for the 3 s most probable radius that we're looking at.

同样的，我们可以看到相同的行为,ｄ轨道的，最可能半径，比ｐ轨道小，3p轨道的,最可能半径,比3s轨道离原子核更近。
