carbon dioxide

How much carbon dioxide you save, if any, depends on how far you live from work and how you get there, among other things..如果真有的话，你可以节约多少二氧化碳？ 它取决于你住得有多远还是你如何完成目标抑或其他因素？

And then we have gas cooled reactors which can use supercritical carbon dioxide or helium..然后我们有气体冷却反应堆,那能使用超临界二氧化碳或者氦。

But as Solomon and colleagues suggest in a new study published in the Proceedings of the National Academy of Sciences, it is not true for the most abundant greenhouse gas: carbon dioxide..但是，正如所罗门和他的同事提出的一项发表在《美国国家科学院院刊》的新研究表明，对最丰富的温室气体，二氧化碳，这是不正确的。
