Learner notes
Memory Tip
记忆联想：弹吉他时轻触弦的中点，发出的清亮高音就是 harmonic（泛音/谐波）——它是基频的整数倍成分。
Context & Register
语域：mixed 常见场景：physics/audio electronics、music (bowed string instruments)、mathematics harmonic 作名词时多用于专业或技术语境，而不是日常口语。在物理学或电子工程中通常指“谐波”；在音乐领域，尤其是指弓弦乐器演奏时，指“泛音”；在数学中则指“调和函数”。整体属于正式、书面的用法，日常对话中较少出现。
Grammar Note
常以复数形式出现
Pronunciation & Spelling
这些词都以 -onic 结尾，重音在 -on- 上，韵脚 /ɒnɪk/ 与 harmonic 相同。注意谐音词 harmonica /hɑːˈmɒnɪkə/ 多一个 /ə/，harmony /ˈhɑːməni/ 结尾不同，都不算同韵。
Usage priority
Collins 词频等级为 1，建议结合例句记忆，而不是只背中文释义。
