Their songs are distinct, too. They use the same range of frequencies, but different syllables.

此外它们的鸣啭也截然不同，使用的频率范围是相同的，但音节不同。

The cochlea in a Tyrannosaurus Rex is 2.5 centimetres long, so it can pick up a wide range of frequencies.

雷克斯霸王龙的耳蜗长2.5厘米可接收到很宽的频段。

Spotting more complex substances was almost impossible because their rotational energy is scattered by their numerous bonds across a wide range of frequencies.

而鉴别更复杂的物质几乎不可能，大量化学键占有很宽的频率范围，以至于旋转能被散射掉。

It usually plays at around 70 to 95 beats per minute and falls within this range of frequencies.

它通常以每分钟 70 到 95 次左右的速度播放，并且属于这个频率范围。

Objects actually radiate energy that covers a whole range of frequencies on the electromagnetic spectrum – all different kinds of light.

事实上，物体发出的能量包括电磁波的所有波频率——所有不同类型的光。

So what we found is that each individual scale will resonate at slightly different frequencies-and that, collectively, they actually absorb a really broadband range of frequencies.

因此，我们发现，每个鳞片的共振频率都有细微的差别，而且加在一起，它们能吸收的（声波）频率范围就很大了。

He invented FM radio, a technology that allowed stations to send a broad range of frequencies that greatly improved the quality of the music.

他发明了 FM 收音机，这项技术允许电台发送范围广泛的频率，从而大大提高了音乐的质量。

Modulation in this range of frequencies from about 12 to 30 hertz are called Beta Rhythms. Our brainwaves modulate at this rate when we're awake and alert.

从大约 12 到 30 赫兹的频率范围内的调制称为 Beta 节奏。当我们清醒和警觉时，我们的脑电波以这种速率调制。

And we played sound at a little strand of spider silk and found that when the silk is very thin, it moves with the air in a sound field amazingly well over a wide range of frequencies, from 1 hz to 50 khz.

我们在一根细小的蛛丝上播放声音，发现当蛛丝很薄时，它会与声场中的空气一起运动，频率范围很广，从1赫兹到50千赫。
