Context & Register
语域：formal 常见场景：化学与营养学文献、学术或技术说明 unsaturated 多用于正式或技术性语境，如化学、营养学或工程描述；日常口语中较少使用。在化学中常表示溶液未饱和或有机化合物含双键/三键。
Pronunciation & Spelling
真正押韵的词只有 saturated，它的重读音节和结尾与 unsaturated 完全一致。related、updated、created 也以 /eɪtɪd/ 结尾，但重音不同，所以不算严格押韵。注意 unsalted /ʌnˈsɔːltɪd/ 和 unrated /ʌnˈreɪtɪd/ 拼写与 unsaturated 很像，但读音差别很大。
