Water, carbon dioxide, and volatile gases combine to create smoke.

水、二氧化碳和挥发性气体结合会产生烟雾。

Whirling galaxies will spark star-fire from drifting motes and volatile gas.

旋转的星系将从漂流的微尘和挥发性气体中引发星火。

These organic molecules break down into simpler molecular components and release volatile gases, which evaporate easily and are combustible.

这些有机分子分解成更简单的分子成分并释放出易挥发的气体，这些气体很容易蒸发并可燃。

Two  devices generate oxygen by electrolyzing water, while carbon dioxide and other volatile  gases are absorbed and vented into space.

两个装置通过电解水产生氧气，而二氧化碳和其他挥发性气体被吸收并排放到太空中。

This initiates the pyrolysis step, but doesn’t really cause combustion, since there’s not much oxygen for the volatile gases to react with.

这会启动热解步骤，但不会真正引起燃烧，因为挥发性气体反应所需的氧气不多。
