此方法属于单相检测法，先提取电网电流中的某相基波幅值，再将基波幅值乘以与该相电流同相位的正弦波，从而得出该相的瞬时基波电流。
This is a single-phase measurement that multiplies the amplitude of fundamental current of a line by a sine signal which has the same phase with the current.
在某些情况下，这些波至的残余会叠加在一起给出近于水平的同相轴。
In some cases residuals from these arrivals will stack up to give nearly horizontal alignments.
地震能量多次反射波的一种类型，表现为一个同相轴。
A type of multiply-reflected seismic energy that appears as an event.
相对而言，它们不受多路径消除效应的影响，例如当返回的强反射波与直接路径信号不同相位时，降低了接收机中的信号强度。
They are relatively immune to multipath cancellation effects, such as when a strong reflected wave arrives out of phase with the direct path signal, reducing the signal strength in the receiver.
回转波这一名称是指在未偏移的地震数据中同相轴的形态。
The name was coined for the appearance of the event in unmigrated seismic data.
回转波这一名称是指在未偏移的地震数据中同相轴的形态。
