语域：formal 常见场景：formal essays、literary descriptions、scientific or technical writing dissipate 多用于正式的书面语，尤其指雾气、云层等逐渐消散，或抽象事物（如疑虑、紧张情绪）散去；日常口语中更常用 disappear 或 fade away。
Rhymes with participate (/pɑːrˈtɪsɪpeɪt/) and anticipate (/ænˈtɪsɪpeɪt/): all share the same stressed-vowel-to-end sound /ɪsɪpeɪt/. Spelling lookalikes constipate (/ˈkɒnstɪpeɪt/) and emancipate (/ɪˈmænsɪpeɪt/) also end in -ipate but have different stressed vowels (and constipate has an extra /nst/), so they do not rhyme.
