记忆技巧Memory Tip
记忆：assay 拼写里藏着 say，化验报告就是要“说”出成分。
语境与语域Context & Register
语域：formal 常见场景：laboratory analysis、mining and metallurgy、pharmaceutical testing assay 作名词时通常用于专业或正式场合，指“化验、分析、测定（物质成分）”，比日常的 test 更正式；在实验室、矿业、医药研发等场景比较常见。
发音与拼写Pronunciation & Spelling
与 assay /ˈæsi/ 真正押韵的是 sassy、classy、brassy、glassy，它们都以 /æsi/ 结尾（重音在首音节）。注意拼写相似的 essay /ˈɛseɪ/、array /əˈreɪ/ 中 ay 读 /eɪ/，不押韵；ass /æs/ 也没有末尾 /i/ 音。
