这种区分类似于前面的稳定轨道图形。

This classification is the analogy of our previous picture of stable orbits.

讨论了不稳定不动点邻域的不稳定轨道的稳定问题。

The stabilization of an unstable periodic orbit in a neighborhood of an unstable fixed point is studied.

自上世纪六十年代起，研究者们就开始研究在这种带电旋转的黑洞内的光子稳定轨道。

Since the 1960s, researchers have determined stable orbits for photons inside these charged, rotating black holes.

The reason this an exception is because it turns out that half filled d orbitals are more stable than we could even predict.

这个例外的原因是因为,半填充d轨道比,我们预期的填充方式更加稳定。

You wouldn't be expected to be able to guess that this would happen, because using any kind of simple theory, we would, in fact, predict that this would not be the case, but what we find experimentally is that it's more stable to have half filled d orbital than to have a 4 s 2, and a 3 d 4.

你们不用预期有能力,猜出这个会发生，因为使用任一种简单的理论，我们事实上可以预测不会是那种情况，但是我们在实验中发现的,是半填充d轨道比,4s23d4更加稳定。
