其他行星上没有氧气，这意味着这些行星缺乏保护生命体免受紫外线辐射的臭氧层。

The absence of oxygen on other planets means that those planets lack an ozone shield to protect life forms against UV radiation.

在火星和我们太阳系的其他行星上没有氧气，这意味着这些行星也缺乏保护地表生物免受紫外线辐射的臭氧层。

The absence of an oxygen atmosphere on Mars and other planets in our solar system means that these planets also lack an ozone shield that would protect surface-dwelling life from UV radiation.

OK, so we've got UV light here, and let's see what we can see, and we lose electrons, if that's what's happening.

好了，我们已经有了紫外光源，让我们来看看能观察到什么，如果那些事情发生了，我们将会失去电子。

We know that UV light gets absorbed by glass, so it shouldn't be able to go through the glass.

我们知道紫外光会被玻璃吸收，所以它无法通过玻璃。

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。
