So, ideally what we did see was, in fact, it does have enough energy with the UV lamp, it wasn't a dramatic shift you saw because we didn't start very high and then it went to that stuck point.

所以，理想上我们所看到的，事实上，紫外灯没有足够的能力，因为我们没有从非常高开始,所以它没有一个特别显著的移动,然后它又回到了黏着点。

So that means we're going to need to figure out what is the energy per photon that's emitted by that UV light.

所以那意味着我们将需要,计算出从紫外光源发射出的,每个光子的能量。
