By using Fourier transform method, the Green function of a point harmonic force applied at a bi-material plane is obtained.

利用积分变换方法得出了两相材料中作用简谐集中力时的格林函数。

The arc furnace electric system will make appearance of more harmonic current at the series resonant point and the parallel resonant and influence of series resonant is larger for the system.

当电弧炉电气系统在串联谐振点和并联谐振点附近时，均会出较大谐波电流，而串联谐振对系统的影响更大一些。

During the process of the identification for the fourth harmonic point, the usage of any element will not affect its uniqueness.

在第四调和元素的确定过程中，任意元素的用法是不影响第四调和元素的唯一性的。

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。
