对应用程序的需求是不一致的，并会经历峰谷。

Demand for the application would be inconsistent and experience peaks and valleys.

我这里是基线分离度，但各论描述的是峰谷比。

I observe baseline separation when the monograph describes a peak-to-valley ratio.

尽管波动不算太大，却足以令峰谷之间产生差异。

Though the fluctuation is not vast, it is enough to make a difference from peak to trough.

So, for example, we have this average level, and then it can go high where we have the peak, or it can go very low. We can also discuss sound waves, so again it's just the periodic variation of some property -- in this case we're talking about density, so we have high density areas and low density areas.

例如这是平均位置，在峰的位置水位高，在谷水位低，我们也可以,讨论声波它也是某种,量的周期变化，在这里我们,讨论的是密度,我们有高密度区和低密度区。
