化学生物科学
n.名词
U〈化〉氮a gas that is a simple substance, without color or smell, that forms most of the Earth's air
Noun:
a common nonmetallic element that is normally a colorless odorless tasteless inert diatomic gas; constitutes 78 percent of the atmosphere by volume; a constituent of all living tissues1790年，法国化学家查普塔从硝石niter中获得一种新气体，便把它命名为nitrogen，字面意思就是“组成硝石的物质”。
用作名词 n.
形容词+～colorless nitrogen无色气体～+名词nitrogen dioxide二氧化氮nitrogen fixation固氮法nitrogen oxide氧化氮
钱博士nitr硝石+o连接字母+gen产生→组成硝石的物质⇒氮
词根nitr-硝来自希腊语。词根gen-产生，起源，生殖，出生，种族，血统来自希腊语，和拉丁词根gen-/gener-产生，起源，生殖，出生，种族，血统及日耳曼词根kin-家庭、氏族最终都源自原始印欧语词根*gene-生，辅音字母k-g相通。
词源解释1790年，法国化学家查普塔从硝石niter中获得一种新气体，便把它命名为nitrogen，字面意思就是“组成硝石的物质”。非常记忆ni你+tro兔肉+gen根⇒吸入氮气的你狂吃兔肉和树根nitr硝石+o连接字母+gen产生→组成硝石的物质⇒氮。词根记忆nitro含氮的+gen产生→氮谐音记忆音“拿吹井”⇒拿氮气吹井近义词 n字母nair空气
