The terrestrial atmosphere is a thin layer of gas (Fig. 2.1) which protects the surface of our planet from lethal interactions with outer space and permits the ambient temperature to be maintained between that of boiling water and ice. It is a nicely tuned system that has been autoregulating its composition and temperature for billions of years.The volatile elements discussed here are those defined as atmophile elements by Viktor Moritz Goldschmidt. They include H, C, N, S, halogens, and noble gases. It is more appropriate to refer to them as the surface inventory of volatiles rather than...

2.大气和海洋的双重起源

地球大气是一层薄薄的气体（图2.1），可以保护我们的行星表面免受与外层空间的致命影响，并使周围的温度保持在沸水和冰之间。这是一个经过精心调校的系统，已经可以自动调节其成分和温度数十亿年。这里讨论的挥发性元素是由Viktor Moritz Goldschmidt定义为亲热元素的那些。它们包括H，C，N，S，卤素和稀有气体。将它们称为挥发物的表面清单而不是...更合适。
