探险家们甚至需要戴上特殊的面具来保护自己不受洞穴里气体的伤害。
Explorers even need to wear special masks to protect themselves from the gases in these caves.
二氧化碳之类气体的排放应该被控制在目前的水平上。
The emission of gases such as carbon dioxide should be stabilized at their present level.
废纸会导致一种有害气体的释放。
气体的来源？是她的新厨柜和铺满整个地板的地毯。
The source of the gas? Her new kitchen cabinets and wall-to-wall carpeting.
为了减缓全球变暖的现象，需要减少温室气体的排放。
In order to reduce global warming, emission of greenhouse gases needs to be reduced.
后来一些天文学家提出，大气中的氨可能起到温室气体的作用。
Then some astronomers came up with the idea that atmospheric ammonia might have acted as a greenhouse gas.
面对全球变暖的问题，人们都将精力集中在规划各种策略以减少温室气体的排放。
In face of global warming, much effort has been focused on reducing greenhouse gas emissions through a variety of strategies.

A bluish ribbon of light stretching from left to right across the picture might be a knot of gas ejected by the supernova.
然而，如果不能全面解决温室气体的排放问题，那么今世后代都将面临着无法估量的风险。
Failure to address comprehensively the problem of greenhouse gas emissions, however, exposes all generations, present and future, to incalculable risks.
他感兴趣的是个体差异，不仅对肠胃气的总量感兴趣，而且对构成气体的百分比也感兴趣。
He was interested in individual differences, not just in the overall volume of flatus, but in the differing percentages of constituent gases.
当一座加油站被烧毁，你不仅想知道是谁扔下了烟头，你还想了解所有易燃气体的泄露原因。
When a petrol station burns down, you don't just want to know who dropped the cigarette; you want to know why all the combustible fumes escaped.
它的学名是肠胃胀气，不过英语里有一套令人印象深刻的生动说法来形容这种消化气体的排放。
Its scientific name is flatus, but the English language has an impressive range of colorful terms to describe the explosive emission of digestive gas.

By studying these components, scientists have obtained a detailed archive of many aspects of climate, including air temperatures, snowfall, and concentrations of greenhouses gases in the atmosphere.
此外，由于气体的分子运动依赖于温度，在木星行星的低温下，即使是最轻的气体也不可能获得逃逸所需的速度。
Also, because the molecular motion of a gas depends on temperature, at the low temperatures of the Jovian planets even the lightest gases are unlikely to acquire the speed needed to escape.
当井和一个水池相接时，油通常会从井里上升，因为它与井下的水的密度不同，或者因为停留在它上方的膨胀气体的压力。
When the well reaches a pool, oil usually rises up the well because of its density difference with water beneath it or because of the pressure of expanding gas trapped above it.
