Greenhouse gas emissions from shale gas are predominantly down to two things: carbon dioxide produced when the gas is burned, and methane that leaks out while the well is being exploited.
页岩气所排放的温室气体主要有两类：燃烧产生的二氧化碳以及页岩气井开采过程中的甲烷泄漏。
It is one of the world's biggest reservoirs of carbon dioxide, the principal greenhouse gas, as well as a rain factory for all of South America and, possibly, a vital regulator of the world's weather.
不仅是全球主要温室气体二氧化碳最大的储藏所之一，也是整个南美洲的降雨工厂，还可以算得上全球气候举足轻重的调节者。
Its geology is ideally suited to storing carbon dioxide—in depleted oil-and-gas fields in the North Sea, as well as in saline aquifers, deep porous rocks full of salty water.
英国地理上对封存二氧化碳十分理想，可存入北海已废弃的油气田、地下盐碱含水层或是充满盐水的深层多孔岩石。
As well as carbon dioxide, planes emit nitrogen oxide, another nasty gas.
除了二氧化碳，飞机还释放出另外一种有害气体——一氧化碳。
Is one of the world's biggest reservoirs of carbon dioxide, the principal greenhouse gas, as well as a rain factory for all of South America and, possibly, a vital regulator of the world's weather.
不仅是全球主要温室气体二氧化碳最大的储藏所之一，也是整个南美洲的降雨工厂，还可以算得上全球气候举足轻重的调节者。
Carbon dioxide increases the acidity of its environment, which could help it eat its way out of apparently secure barriers well before the gas becomes neutralized over 10, 000 years.
二氧化碳在储存一万年以上时会变成中性，但它本身会增加其环境的酸性，这将帮它逃出看似安全的隔离井。
When there are both carbon dioxide and hydrocarbon in the different intervals in one well, it is better to use this method to determine the gas types.
当一口井的不同层位同时存在二氧化碳气和烃类气时，使用该方法来确定气体的类型，效果较好。
A well-stimulation treatment in which a gas, usually carbon dioxide or nitrogen, is mixed with water and acid and pumped down a well.
一种气体(通常为二氧化碳或氮气)与水和酸混合并沿井向下泵入的井增产处理。
The leading-in system for the feed gases hydrogen and carbon dioxide as well as the protection shielding gas nitrogen for the process operation is standing outside the container.
对于原料气体氢气、二氧化碳以及操作的时候保护气体氮气来说，导入系统是置于机箱外面的。好了就这样了。不过说实话，原文有些问题。
