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。

The sound intensity distribution in the sound field of two closely spaced simple harmonic point sound sources have been studied in this paper.

本文讨论了相距很近的两个点声源的声强分布，发现位于声源之上的平面法向声强在某些区域为负向声强。

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。
