Oxidation is the process of combining with oxygen, or of making something combine with oxygen. The picture everyone knows is rust: iron meets air and water, joins with oxygen, and the metal goes brown and weak.

Oxidation氧化 is the process of combining with oxygen, or of making something combine with oxygen是跟氧結合，或讓某樣東西跟氧結合的過程。The picture everyone knows is rust大家最熟悉的畫面就是生鏽 iron meets air and water, joins with oxygen鐵接觸到空氣和水，跟氧結合 and the metal goes brown and weak讓金屬變成褐色又脆弱。

Chemists use the word more widely — not only rust, but many other “joining with oxygen” changes, and later in school science it also covers related changes that do not always look like rust at all. You hear it in science class, in talk about metal going bad, and sometimes about food or old paint.

Chemists use the word more widely化學家用這個詞的範圍更廣 not only rust, but many other "joining with oxygen" changes不只是生鏽，還有很多其他「跟氧結合」的變化 and later in school science it also covers related changes that do not always look like rust at all到了學校科學課裡，它還包含一些看起來完全不像生鏽的相關變化。You hear it in science class, in talk about metal going bad, and sometimes about food or old paint你會在科學課、講金屬變質的時候聽到它，有時候也用在食物或舊油漆上。

The everyday noun is oxidation (the process); the verb is oxidize; the stuff you often get is an oxide. It is a school-and-science word, not a kitchen-table word, though the rust example is something everyone has seen.

The everyday noun is oxidation (the process)日常用的名詞是oxidation（氧化，指這個過程） the verb is oxidize動詞是oxidize（氧化） the stuff you often get is an oxide常常產生出來的東西叫oxide（氧化物）。It is a school-and-science word, not a kitchen-table word這是學校、科學用的詞，不是餐桌上會聊的詞 though the rust example is something everyone has seen不過生鏽這個例子大家都親眼見過。

Though actually rust is only oxidation of iron; a sliced apple turning brown is a kind of oxidation too.

Though actually不過其實 rust is only oxidation of iron生鏽只是鐵的氧化 a sliced apple turning brown is a kind of oxidation too切開的蘋果變褐色其實也是一種氧化。
