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

哦，我懂了，多普勒效应嘛。

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。

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。

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。

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。

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。

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。

For example, we created this running sound with frequent gaps so that people with visual impairments could locate their robots using the Doppler effect.

例如，我们创建了这种带有频繁间隙的运行声音， 以便有视觉障碍的人可以使用多普勒效应定位他们的机器人。

Indeed, the police make use of the Doppler effect to measure the speed of cars by measuring the wavelength of pulses of radio waves reflected off them.

事实上，警察利用多普勒效应通过测量汽车反射的无线电波脉冲的波长来测量汽车的速度。

The team first noticed the anomaly because of the Doppler effect, which describes how the frequency of light admitting from an object changes if the object is moving.

由于多普勒效应， 该团队首先注意到了异常现象，多普勒效应描述了物体移动时从物体进入的光的频率如何变化。

The system would then measure with ultimate precision how long it takes the beams to be reflected back, and would then apply the Doppler effect in three-dimensional space to proceed safely.

然后，该系统将以极高的精度测量光束被反射回来所需的时间，然后将在三维空间中应用多普勒效应以确保安全进行。
