也许太阳转速正减慢，也许我们得到的能量,不是别的，而是旋转动能。

Maybe the sun is spinning down, is slowing down and maybe the energy that we get is nothing but rotational kinetic energy.

是一个平均的能量，我们就可以得到这个平均能量，如果我们考察，可以占据所有状态，的系统。

It's an average of the energy that we would get by looking at the states that the system might be occupying.

现在，因为我们不只对那些最后，是在这个方向上得到能量的，中子感兴趣。

Now, because we're only interested in those neutrons that end up with this energy going in our direction.

So it's not a continuum of energy that we can have, it's only these punctuated points of energy that are possible.

我们得到的不是一个连续的能量，而是一些分立的可能的能量值。

So, similarly in a case where instead we have a small energy difference, we're going to have a low frequency, which means that we're going to have a long wavelength here.

在这个例子里,能量差较小,我们得到的频率低,这意味这它的波长更长。

We're only using up a little bit to eject the electron, then we'll have a lot left over.

如果我们只需要用很少一部分来发射出电子，那么我们可以得到很多的剩余能量。
