Not this
She has a SM degree in chemistry.
Use this
She has an SM degree in chemistry.
SM 读作 /ˌes ˈem/，以元音音素开头，因此不定冠词要用 an，不能用 a。
Not this
He received his sm in physics.
Use this
He received his SM in physics.
SM 表示理科硕士（Master of Science），是学位缩写，须大写；小写 sm 无法被识别为这一学位缩写，所以应改为大写。
Not this
The chemical symbol for samarium is sm.
Use this
The chemical symbol for samarium is Sm.
化学元素符号必须首字母大写、其余字母小写；samarium 的元素符号是 Sm，小写 sm 不是规范的化学符号。

想记住 sm：S = science，M = master，即“理科硕士”；同时钐的元素符号是 Sm，可联想银灰色的钐金属。
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。
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.
