语境与语域Context & Register
语域：mixed 常见场景：学位证书与简历、化学教材与元素周期表 sm 不是日常口语词，通常以缩略语或符号形式出现：表示理科硕士学位（Master of Science）时多用于学位证书、简历等正式学术文件；表示稀土元素钐（samarium）时常见于化学教材或元素周期表。日常英文中很少单独写小写 sm，具体含义需根据上下文判断。
发音与拼写Pronunciation & Spelling
These words all end in the letters -sm, pronounced /zəm/: prism and schism rhyme, and chasm and spasm rhyme. The headword sm is an abbreviation/symbol, not a spoken word ending in -sm, so it does not rhyme with them.
