methane nitrous-oxide的意思|示意

Take New Zealand where 34.2 million sheep 9.7 million cattle 1.4 million deer and 155 000 goats emit 48 per cent of the country's greenhouse gases in the form of methane and nitrous oxide.

以新西兰为例：该国拥有3400万只羊、970万头牛、140万鹿以及15.5万山羊，这些动物所排放的温室气体占据整个国家温室气体的48%，主要成分是甲烷、氮氧化物。

Animal excrement emits gases, such as hydrogen sulfide and ammonia, that poison the air around farms, as well as methane and nitrous oxide, which are major contributors to global warming.

动物的排泄物释放出的气体，例如氢化硫、氨气、污染了农场周围的空气，同时，甲烷和一氧化氮则是导致全球变暖的主要元凶。

Methane is the most important of these gases, followed by black carbon and nitrous oxide.

甲烷是这些气体的最重要部分，然后才是黑碳和一氧化氮。

That's the case for some of the gases that contribute to climate change, such as methane and nitrous oxide.

对一些造成气候变化的气体，如甲烷和氧化亚氮(一氧化氮，笑气)，来说，情况确实如此。

Others, such as nitrous-oxide emissions fromsoils and methane emissions from animals, cannot.

而另外一些却不能直接检测，比如从土壤中排放的一氧化二氮与从牲口身上排放的沼气。

Barker noted that raising animals for food is one of the largest sources of carbon dioxide and the single largest source of both methane and nitrous oxide emissions.

巴克提到饲养动物作为食物是二氧化碳的一种主要来源，并且是甲烷和氧化亚氮排放的唯一主要来源。
