These are definitely not equally spaced, be even more disproportionate but they should than I have shown it.

它们必然不是被均分的，并且会比我所展示出来的,显得更不均匀。

And as you go to higher and higher levels, those energy levels, as you saw in the case of hydrogen, are more closely spaced.

当能级变得越来越高，那些高能级的轨道，就会变得越来越接近，正像你在氢原子里看到的那样。

And so when they become very, very closely spaced there is mutual repulsion of those electrons.

所以当它们越来越近的时候,这些电子会产生相互的排斥力。

They took a crystal, this is a single crystal of nickel that has regular planes of atoms, and those planes are spaced on the order of an angstrom or less apart, and they irradiated this with x-rays.

他们取了个晶体,一个具有规则原子平面的，镍晶体,这些面间距差不多也是一埃或者更少，它们放射出X射线。
