amplitude 读音:英 [ˈæmplɪtjuːd];美 [ˈæmplɪtuːd] 意思: 物理领域:指振幅,即振动或波动的最大位移。
例如声波、光波等的振动幅度。
更广泛意义:表示丰富;充足;广大;规模大等含义。
网络释义:在物理学、工程学、数学等多个学科领域频繁出现,用于描述周期性现象的强度、范围等特征量。
在信号处理中,代表信号的强弱程度;在天文学中,可用于描述天体某些周期性变化的幅度大小等。
常用搭配短语: amplitude modulation (AM):调幅,是一种调制方式,常用于无线电广播等领域。
例如:Amplitude modulation was widely used in early radio communication.(调幅在早期无线电通信中被广泛使用。)
