There have always been slight oscillations in world temperature.

全球气温一直在轻微地波动。

The amplifier has a power isolation circuit and bandwidth limiting to reduce oscillations and motorboating.

该放大器具有电源隔离电路和带宽限制，以减少振荡和汽船排气声。

Here I have 256 oscillations per second.

这里是震动256，次每秒。

I got it low because I measured ten oscillations, you see?

我让它变低了，因为我做了10次振荡，看到了么？

So we can calculate now what the period of oscillations is.

因此现在可以计算，震荡的周期是多少。
