Oh, sure, I see it now. The Doppler effect.

哦，我懂了，多普勒效应嘛。

I don't care if anybody gets it. I'm going as the Doppler effect.

我不管别人懂不懂，我就是要穿成多普勒效应。

The Doppler effect is the frequency shift heard as a source of sound approaches or recedes.

多普勒效应是当声源靠近或后退时听到的频率偏移。

You're probably familiar with the Doppler effect; the change in pitch when, say, a motorcycle goes by.

你们可能熟悉多普勒效应；即音高的变化，例如摩托车经过时的音高变化。

A slight shift in the frequency, because of the Doppler effect, means its speed and direction can be measured too.

由于多普勒效应，返回信号的频率有微小变化，这就意味着飞行器的速度和飞行方向也可以被测量出来。

But you would experience a cool Doppler effect around you.

但是你会在你周围体验到很酷的多普勒效应。

Finally, we covered decibels, as well as the Doppler effect.

最后，我们还谈到了分贝 多普勒效应。

The Doppler effect isn’t unique to sound waves, though -- it happens with light, too.

不过，多普勒效应并不是声波独有的——它也会发生在光中。

The Doppler effect isn't unique to sound waves, though -- it happens with light, too.

多普勒效应不仅限于波 不仅有声音，还有光。

You could put it in the tape deck you used to teach us about the doppler effect.

你可以把这个放入磁带机你之前用它教过我们多普勒效应。
