A nitrate is a kind of chemical stuff that holds nitrogen and oxygen in a certain shape. Farmers put nitrate fertiliser on fields because plants are hungry for it and grow better. Some food, like ham, is kept longer with a nitrate.

A nitrate硝酸鹽 is a kind of chemical stuff是一種化學物質 that holds nitrogen and oxygen in a certain shape以某種結構包含氮和氧. Farmers農夫 put nitrate fertiliser on fields把硝酸鹽肥料施在田裡 because plants are hungry for it因為植物需要它 and grow better而且能長得更好. Some food一些食物, like ham像火腿, is kept longer with a nitrate用硝酸鹽處理後可以保存更久.

You will also meet the word in science class and in news about farms. Though actually the same family of chemicals can be dangerous: some nitrates, stored badly, can explode.

You will also meet the word你也會在 in science class and in news about farms自然課和有關農業的新聞裡看到這個詞. Though actually不過事實上 the same family of chemicals這一整類化學物質 can be dangerous也可能很危險: some nitrates有些硝酸鹽, stored badly如果保存不當, can explode可能會爆炸.

As a verb當動詞用時, to nitratenitrate這個字 is a lab word是實驗室用語: to treat something with this kind of chemical指用這種化學物質處理某個東西, or to turn it into a nitrate或是把它變成硝酸鹽. Most learners大部分學習者 only need the noun只需要學名詞就好. The verb動詞 belongs to chemistry people是化學圈的人在用的, and even they do not use it as much as the noun而且連他們用動詞都不如用名詞頻繁.

It is a school-science and news word, not everyday chat.
