幅值是在一个周期内，交流电瞬时出现的最大绝对值，也是一个正弦波，波峰到波谷的距离的一半。信号的参数一般是用幅值和频率表示；频率就是单位时间内的周期数。
网络释义专业释义
...阻性电路（resistivecircuit）：在交流电路中，如果电路中总电压与总电流同相，则称电路为阻性电路。35幅值（amplitude）：也称最大值，是正弦量在随时间变化的整个过程中所达到的最大值。

However, as a typical non-stationary signal whose amplitude and frequency components varied with time, the instantaneous peak amplitude of strong ground motion could not represent its destructive power perfectly.
但是,地面运动是一种典型的非平稳信号,幅值和频率成分均随时间变化,瞬时的幅值最大值并不能完全代表其破坏能力。

So, regardless of the type of wave that we're talking about, there's some common definitions that we want to make sure that we're all able to use, and the first is amplitude.
所以，不管我们讨论的,是哪种波，它们都有一些我们,能用到的共同的定义,其中第一个就是幅值。
-
So, sometimes people get confused when they're solving problems and call the amplitude this distance all the way from the max to the min but it's only half of that because we're only going back to the average level.
解题的时候会弄错，把这个从,最大值到最小值的距离,叫做幅值，但实际上,只有它的一半,只是它和平均值的差距。
