我们意识到这样的一小点能量激发产氢过程，进而依靠自身维持下去。

We realised that just a little bit of that energy could make this process go on its own.

燃料棒外层可能也已点燃，产生足够的能量激发辐射性燃料向外扩散。

The outer shell of the rods could also ignite with enough force to propel the radioactive fuel inside over a wide area.

惰性气体分子暂时结合到反应性气体，形成了自发地或通过刺激释放能量激发的化合物。

The inert gas molecules temporarily bind to the reactive gases, forming excited compounds that release energy either spontaneously or by stimulation.

We're going to release a lot of energy for bonding, it's going to more than make up for the fact that we actually had to spend some energy to promote that electron.

在成键时，会释放大量能量,这比补偿激发电子,的能量要多。

putting all those things together, if you looked at this question again we'd get 100% on it, 0 9 that our only option here is 0. 9, and that it's not the negative, it's the positive version, because we're talking about how much energy we have to put into the system in order to eject an electron.

把这些放在一起，你们再看一下题目,大家100%都能选对，我们唯一的选择就是这个，它不是负数，它是正的，因为我们说的，是要,把电子激发出来,需要提供的能量。

So if we're going to eject an electron using a minimum amount of energy, that's where it's going to come from.

因此，如果我们要用最少的能量,激发出一个电子，那这个电子一定是，2，p，轨道上的。
