Man-made Gas的意思|示意

The greenhouse gas figure equates to 18% of man-made greenhouse gas emissions, largely thanks to the methane and nitrous oxide animals' "enteric fermentation".

畜牧业产生的温室效应气体，大部分由甲烷沼气和动物肠内发酵及粪尿处理产生的氮氧化物，总量占到人为产生温室气体的18%。

Including man-made emissions, the Earth’s “carbon cycle” releases about 330 billion tonnes of the gas each year.

地球上的“碳循环”，包括人类社会的排放在内，每年大约释放出3300 亿吨的二氧化碳，其中的大多数是被当代所谓的“碳汇”（是指从大气中清除二氧化碳的过程、活动或机制）吸收掉。

This opens the door to quantifying greenhouse gas emissionsmade from a variety of natural and man-made sources.

这就为温室气体自然和人为排放的各种来源的量化开了方便之门。

And the cause is clear, say the authors: 'It is very likely that [man-made] greenhouse gas increases caused most of the average temperature increases since the mid-20th century,' says the report.

原因是显而易见的，作者说：“自从20世纪中叶，很有可能是[人造的]温室气体的增多导致大多数平均气温的提升。”，报告说。

Man-made static magnetic fields are generated wherever DC currents are used, such as in electric trains or industrial processes such as aluminium production and in gas welding.

在使用直流电的地方即产生人为的静电磁场，例如在电车或诸如铝生产和气焊等工业操作程序中。

Partly it's growing evidence that feedback loops amplifying the effects of man-made greenhouse gas emissions are stronger than previously realized.

另一部分是因为有关人造温室气体排放带来的影响在反馈循环系统中不断扩大的证据在不断增加，比之前意识到的更为严重。
