Cooling systems use gases called refrigerants. Such gases can affect the atmosphere if they escape.

冷却系统使用一种叫制冷剂气。如果这些气，可能会影响大气。

Same as when you're boiling a pot of water, when it goes from cold to hot and it bubbles, you start to see the gases come off.

和煮一壶水一样，从冷到热，它们会冒气泡，你可以看到气。

A volcanic vent is a place on the Earth's surface where lava or gas can escape.

火山喷口是地球表面熔岩气地方。

Light that isn't reflected is instead absorbed, heating the volatile material  beneath the dust layer, causing outgassing of water and carbon dioxide, which also blasts  the tiny dust particles Rosetta picked up into space.

未被光线则被吸收，加热了尘埃层下挥发性物质，导致水蒸气和二氧化碳，这些气同时也将罗塞塔探测器采集到小尘埃颗粒喷入太空。

And when you tilt your glass while you pour your beer, you’re stopping most of the remaining gas from escaping.

如果您在倒啤酒时倾斜玻璃杯，就可以阻止大部分剩余气。

If the rocks are volcanic, they could be tiny vessels left over from gases that escaped, called vesicles.

如果岩石是火山岩，它们可能是气遗留下来微小容器，称为囊泡。

A little bit of a bang, but that's just bang of the gas escaping, it didn't burn.

有点爆炸声，但那只是气声音，没有燃烧。
