波周期 meaning in English

period of wave
wave period

The higher modes have shorter periods than the fundamental mode and, moreover, they have higher velocities .
高振型波比基阶振型波周期短，波速高。
Significant wave period
有效波周期
It is capable of detecting the value of both the fluctuation voltage and the fluctuant power
该方法可检测出每个调幅波周期中的电压波动值，并且能计算波动功率。
The wave period in shallow water keeps constant , but the decrease of wave length must be calculated by alternative method
摘要浅水波周期保持常值，而波长缩减时其计算需进行迭代。
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。
