wave(波) + form(形状)，波形就是波画出的形状，像示波器上的曲线。
Context & Register
语域：formal 常见场景：electronics、signal processing、physics 这是专业术语，通常用于电子、信号处理或物理等领域的书面或正式场合，日常口语中比较少见。
Pronunciation & Spelling
waveform 的重音在第一个音节 /ˈweɪv-/，所以它并不与 form、storm、warm 构成整词同韵。后一半 -form 的读音为 /fɔːm/，与 form、storm 同音（英式）；warm 读 /wɔːm/，元音相同。platform 末音节也是 /fɔːm/，但重音在首，conform 虽拼写以 -form 结尾，重音却在最后，注意不要只看拼写判断读音。
