1.亚硝(酸)的;含有三价氮的
1.made from or containing nitrogen, especially in a low valence state
1.As if that weren't bad enough, the bacteria that thrive in low oxygen conditions emit a powerful greenhouse gas, nitrous oxide.
如果这还不够糟的话，细菌在低氧环境下迅速滋长会释放一种温室气体，一氧化二氮，俗称“笑气”。
2.Surgeons who have used nitrous oxide anesthesia to do so have been full of ear-piercing cries of the operating room, filled with a laugh.
外科医生们纷纷用笑气做麻醉药，使本来满是刺耳的喊叫声的手术室，弥漫着一片笑声。
3.The invention relates to a co-al composite oxide supported gold catalyst for nitrous oxide decomposition and a preparation method thereof.
本发明涉及一种用于一氧化二氮分解的钴铝复合氧化物负载金催化剂及其制备方法。
4.But two-thirds of this effect may be offset by the greater release of nitrous oxide, a potent greenhouse gas, from the sea.
但是这个效应的三分之二可能被从海洋排出的温室效应的主要气体-氧化亚氮的大量排放所抵消。
5.If you inhale too much nitrous oxide very quickly, the gas can completely shut down the area of your brain responsible for breathing.
如果快速吸入过多一氧化氮，它就能完全封锁你的大脑对呼吸的控制。
6.While nitrous oxide is a powerful greenhouse gas, when it's burned as rocket fuel, the only byproducts are hot oxygen and nitrogen.
虽然氧化氮是种温室效应气体，但当用作火箭燃料燃烧时，排出的副产品仅仅是热氧气和热氮气。
7.Stanford professor Brian Cantwell specializes in designing rocket thrusters that run on nitrous oxide, also known as laughing gas.
斯坦福大学教授BrianCantwell致力于设计开发以氧化氮又称笑气为动力的火箭推进器。
8.But the quantification of nitrous-oxide emissions is still not well understood, says Dr Williams, so it is not clear which model to use.
但是，威廉姆博士说，一氧化二氮气体的具体排放量目前还没有人们完全了解，因此也无法决定该具体使用哪一种模拟方式。
9.He and some of his grad students wanted to use nitrous oxide as an emissions-free energy source.
他和他班上一些大学生想利用氧化氮作为无排放的动力能源。
10.Agriculture is responsible for between half and two-thirds of emissions of two especially toxic greenhouse gases, methane and nitrous oxide.
农业对二分之一到三分之一的特别是两种有毒气体的排放负责，甲烷和氧化亚氮。
