记忆技巧Memory Tip
Tb（大写 T 小写 b）是元素铽；TB（两个都大写）是肺结核/太字节。记住：大小写不同，意思不同。
语境与语域Context & Register
语域：mixed 常见场景：医学语境：结核病、计算机语境：太字节 tb 是缩写，通常写作 TB，读作 /ˌtiːˈbiː/。在医学语境多指结核病，在计算机语境多指太字节；本身没有明显的正式或口语之分，主要由使用领域决定。正式文本中通常先写全称再使用缩写。
发音与拼写Pronunciation & Spelling
“tb” is pronounced as two letters: /ˈtiˌbi/, so it rhymes with words ending in the /iː/ sound, such as bee, key, tea, see, tree, free. Be careful with lookalikes like “tab” (/tæb/) and “tub” (/tʌb/), which share the “t_b” spelling but sound completely different.
