We have literally altered the chemistry of our planet's atmosphere.

我们实际上改变了地球大气层的化学成分。

These different instruments also probe different layers of the atmosphere so that ultimately a picture of the chemistry going on between them can be gleaned.

不同的仪器可以探测到大气层中不同层次的成分，因此最终的化学成分图要待到他们收集了所有的信息才能出来。

What the net effect of the altered chemistry of the atmosphere would be is unknown, Penuelas said.

Penuelas说，这种大气层导致的化学信息更改所带来的结果还是未知。

Titan, with a thick atmosphere and a bizarro-world form of weather featuring toxic winds and hydrocarbon rain, is home to a mix of complex chemistry, complete with organic molecules.

土卫六拥有浓厚的大气层和疯狂世界似的气候特征：有毒的风和由碳氢化合物组成的雨水。同时，土卫六海充满着各种复杂的化学成份和有机分子。

My main interest is understanding the chemistry and stability of Pluto's atmosphere.

我的主要兴趣是了解冥王星大气层的化学组成和稳定性。

The sources of methane by monitoring its concentration in the ground atmosphere was analyzed, which provided important bases for the studying in the atmospheric chemistry.

通过监测地面环境空气中甲烷的含量来分析其来源，能够为大气化学的研究提供非常重要的依据。
