In this paper, we divided the double frequency crystal into numerous small double frequency units and derived the harmonic power and the double frequency efficiency in each unit.

本文中将倍频晶体分割成无数多个小倍频单元，并导出每个倍频单元中的谐波功率与倍频效率。

The power converters and other nonlinear loads "inject" the harmonic current into the power systems and cause a series of problems.

电力变流器和其他非线性负荷向电力系统“注入”谐波电流，引起一系列问题。

I want to make one other point before we launch into that, and that is the following: that composers use the rate of harmonic change-- whether it's changing or not changing-- to sort of make us feel different ways about the music that we are listening to.

在此之前我还要说一个问题，不管和声有没有改变，作曲家都能通过和声改变的频率-,让我们对所听的音乐有不同的感受-,它能让我们感受到这段音乐。
