Rectification is the act of putting something right after it has gone wrong — a mistake, an unfair rule, a false report. It is a heavy, formal noun. You find it in news, law, and official letters more than in speech.

Rectification is指 the act of putting something right把某件事情導正的動作 after it has gone wrong在它出錯之後——a mistake, an unfair rule, a false report像是一個錯誤、一條不公平的規定、或一則不實報導。It is a heavy, formal noun這是個沉重、正式的名詞。You find it你會在 in news, law, and official letters新聞、法律、公文裡看到它，more than in speech比在口語裡多。

A person might demand the rectification of an error; a company might publish a rectification when it has printed the wrong facts. You would not ask a classmate for “rectification” of homework; “Please correct this” is the human-sized word.

A person might demand一個人可能會要求 the rectification of an error針對某個錯誤的rectification；a company might publish一家公司可能會刊登 a rectification一則rectification when it has printed the wrong facts當它印錯了事實的時候。You would not ask a classmate你不會跟同學要求 for “rectification” of homework功課的「rectification」；“Please correct this”「Please correct this」（請把這個改正過來） is the human-sized word才是人跟人之間會用的說法。

Though actually, specialists also use it in other rooms: electricians talk about rectification when they turn alternating current into direct current, and chemists may use it for a kind of purifying. Those are extra, technical lives of the same word. The meaning you will meet first is still “making a wrong thing right.”

Though actually不過實際上，specialists also use it in other rooms專業人士在別的領域也會用這個字：electricians talk about rectification電機工程師會在 when they turn alternating current into direct current把交流電轉成直流電時講rectification，and chemists may use it for a kind of purifying而化學家可能會用它來指某種提純的過程。Those are extra, technical lives of the same word這些是同一個字額外的技術性用法。The meaning you will meet first is still你最先會遇到的意思還是 “making a wrong thing right.”「把錯的事情導正過來」。
