With people actually talking about long-range energy planning for the first time in decades, the high-tech carbon-negative nuclear option has a high profile at the moment.

人们数十年来首次真正论及长期能源计划，科技含量高、不排放二氧化碳的核能呼声很高。

"Today,we have signed an agreement, which broadens the reach of our cooperation beyond the supply of nuclear reactors to areas of research and development and a whole range of areas of nuclear energy,".

So anything that goes from a higher energy level to 2 is going to be falling within the Balmer series, which is in the visible range of the spectrum.

任何更高能级到2能级2,都是属于Balmer系，它在可见光谱中。

We can think about the Lyman series, which is 1 where n equals 1. We know that that's going to be a higher energy difference, so that means that we're going to be in the UV range.

我们可以来看看Lyman系,也就是n等于,我们知道它的能量差更大,所以它在紫外光区内。

We have the beginnings of a long-range energy policy and although we still have to catch up after decades of inaction, we are making real progress.
