detection vs discovery
「detection」強調使用技術或方法「偵測、察覺」到某物存在的事實，過程可能隱含主動搜尋。而「discovery」則側重於「發現」一個先前未知或未被注意的事物、地方或事實，常帶有意外或首次知曉的意味。
detection vs identification
「detection」是「偵測到有東西存在」的第一步。而「identification」是後續的步驟，指「辨識、確認出該東西具體是什麼或屬於哪一類」。
detection vs observation
「detection」常涉及使用工具或特定方法來「偵測」可能隱藏、微弱或不易察覺的事物。而「observation」則更通用，指透過感官（尤其是視覺）「觀察」現象或行為，過程可能更被動或持續。
在對話中，當引述或轉述他人關於「發現」或「察覺」的陳述時，常會使用這個詞。 EN: So, after the detection of the issue, the team immediately called a meeting. 翻譯: 所以，在問題被發現之後，團隊立刻召開了會議。
EN:Her detection of the subtle change in his tone made her suspicious.
翻譯:她察覺到他語氣中細微的變化，這讓她起了疑心。
在口語中，有時會用這個詞來強調某個發現是經過努力或使用技術才得到的結果，而非偶然。 EN: It wasn't just a guess; it was a proper detection by the new software. 翻譯: 這不只是猜測，而是新軟體確實偵測到的結果。
EN:The early detection of the disease literally saved his life.
翻譯:這種疾病的早期發現真的救了他的命。
在組織思緒或尋找合適詞語時，說話者可能會用「the detection of...」或「detection here...」這類短語作為停頓填充，引出後續解釋。 EN: The main problem, the detection of the bug, took much longer than expected. 翻譯: 主要的問題，也就是那個錯誤的偵測，花的時間比預期長很多。
EN:Our success hinges on one thing — detection — without it, we're blind.
翻譯:我們的成功取決於一件事——偵測——沒有它，我們就像瞎子一樣。
正式寫作注意：在非常正式或學術的寫作中（如研究論文、官方報告），應避免將「detection」用於上述口語中的停頓填充或過於鬆散的引述結構，以保持文體的嚴謹與簡潔。

×The detection of the virus were accurate.
✓The detection of the virus was accurate.
The subject is 'detection' (singular uncountable noun), so the verb must be singular 'was', not plural 'were'.
×They developed a new technology for detect cancer.
✓They developed a new technology for the detection of cancer.
The preposition 'for' should be followed by a noun or noun phrase. Use 'the detection of' (noun form) instead of the verb 'detect'.
×The system allows a quick detection for errors.
✓The system allows quick detection of errors.
The correct preposition to use with 'detection' is 'of' (indicating what is being detected), not 'for'. Also, 'quick detection' is more natural than 'a quick detection' in this context.
×His detection of the problem saved the company.
✓His detection of the problem saved the company. (Contextually, 'identification' or 'discovery' is often more natural.)
While grammatically correct, 'detection' often implies a systematic or technological process. For a person realizing a problem through observation or thought, 'identification', 'discovery', or 'realization' is more idiomatic.
×We need to make a detection on the source of the noise.
✓We need to detect the source of the noise.
The phrase 'make a detection' is not idiomatic. Use the verb 'detect' directly or rephrase using 'perform detection' (more technical) or simply 'detect'.
