distortion wave meaning in Chinese

畸变波

In this paper , a method assessing harmonic impedance by synchronously layered distortion waves is proposed , which is based on the " fluctuations method " - a simple and effective means . however the method is based on the fourier transform , which can just precisely analyze the signals whose cycle is integer times as broad as that of fundamental wave . with sampling windows widening , the variations of distorted signals in a fundamental period are weakened
本文是以一种被广泛采用的非干预式谐波阻抗估计方法? ? “波动量”法，的基础上，针对现有方法以直接的fourier变换为分析工具，只能对基波周期的整数倍窗口采样信号进行分析，畸变信号在一个基波周期内的变化随采样窗口增大而被弱化，并且，谐波次数越高，分辨率就越低，大大限制了谐波阻抗估计的准确性的提高。
