This increase in temperature with height is due to the absorption of UV solar radiation by ozone molecules.

温度随高度的增加是由于太阳辐射的紫外线被臭氧分子吸收的缘故。

The temperature increase in this layer is mainly caused by the absorption of UV solar radiation by oxygen molecules, which dissociate as a result of this.

该层中温度的增加主要是因为太阳辐射的紫外线被氧分子吸收，分解所致。

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.

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。

But the increased ultra-violet (UV) solar radiation which the damaged ozone allows through to the surface of the earth is a threat to all living things.

Thomas also notes that many shallow-water species went extinct during this epoch, lending credence to the idea that GRB-precipitated solar UV radiation could have been the cause.
