The experimental results shows that phase and amplitude characteristics must be considered in the device designing.

实验结果表明，在声光器件设计时，必须考虑其相位和振幅特性。

In ac circuits, the current amplitude changes continuously that the concept of phase or time becomes very important.

在交流电路中，电流的幅度是连续不断地变化的，因此相位和时间的概念变得十分重要了。

Because complex wavelet transforms can exactly identify amplitude and phase information in signal to be dealt with, they are suitable for detection of fault signals in power system.

复值小波变换能准确分辨出信号中所包含的幅值信息和相位信息，因而，适用于电力系统的故障信号的检测。

"But if you look into the Mekong delta, for example in Vietnam, it has shown the 30-year cycle, but the phase and amplitude is going up and then going up like that."
