Nitrous oxide (N2O),more properly called
dinitrogen monoxide,is a compound with many interesting uses.It was
discovered in 1772 by Joseph Priestley (who is also given credit for
discovering oxygen gas),and its intoxicating effects were noted almost immediately.
In 1798,the 20-year-old Humphry Davy became director of the Pneumatic
Institute,which was set up to investigate the medical effects of various
gases.Davy tested the effects of N2O on himself,reporting that after inhaling
16 quarts of the gas in 7 minutes,he became “absolutely intoxicated.”
Over the next century “laughing gas,” as
nitrous oxide became known,was developed as an anesthetic,particularly for
dental procedures.Nitrous oxide is still used as an anesthetic,although it
has been largely replaced by more modern drugs.
One major use of nitrous oxide today is as the propellant in cans of “instant”
whipped cream.The high solubility of N2O in the whipped cream mixture makes it
an excellent candidate for pressurizing the cans of whipped cream.
Another current use of nitrous oxide is to
produce “instant horsepower” for hot rods and street racers.Because the
reaction of N2O with O2 to form NO actually absorbs heat,this reaction has a
cooling effect when placed in the fuel mixture in an automobile engine.This
cooling effect lowers
combustion temperatures,thus allowing the
fuel–air mixture to be significantly more dense (the density of a gas is
inversely proportional to temperature).This effect can produce a burst of
additional power in excess of 200 horsepower.Because engines are not designed
to run steadily at such high power levels,the nitrous oxide is injected from a
tank when extra power is desired.

氧化亚氮（ N2O ）,更恰当地被称为一氧化二氮,是一种化合物,它有许多有趣的用途.它是由1772年被由约瑟夫·普里斯特利发现的（他也因此受到奖赏） .人们很快意识到N2O可以使人迷醉的功效.
1798年,20岁的汉弗莱戴维成为气动学院主任,进行了对了各种气体医疗效果的调查研究.戴维测试自己吸入N2O的影响的报告种说,吸入后16夸脱（好像是种单位）的气体后他在7分钟内变得完全陶醉了.
在下一个世纪中,被称为“笑气”的一氧化二氮已经成为众所周知的麻醉剂,特别是用在牙科手术中.在现代社会中,一氧化二氮仍被当做麻醉剂而被使用,尽管大部分麻醉剂已经被现代药物所取代.
现在,氧化亚氮的主要用途之一是作为推进剂罐“即时”奶油.N2O在即时奶油中的高溶解度让它很适合用来给推进剂加压.
当前,一氧化二氮的另一个用途是为热棒和街头赛车手产生“即时马力”.因为N2O与O2反应形成NO实际吸收热量,所以有冷却效果.当它被放置在汽车发动机的燃料混合物,它可以有效地冷却发动机.这种冷却会下降燃烧的温度,从而使空气燃料混合物更加的密集（气体的密度是与温度成反比） .这种效应可以产生突发额外的功率超过200马力.因为发动机的设计并不能在如此高的功率水平中稳定运行在,在需要额外动力时,更多地一氧化二氮需要被注入罐中.
