n.千赫
They sat aside 100 channels, each 200 kilohertz wide. 他们在旁边坐了100种渠道,各200千赫宽。
Most telephones reproduce 300 hertz to 3.5 kilohertz. 大多数电话重现300赫兹到3.
Twisted-pair conductors are sufficient if frequencies of interest are below a few hundreds:成百上千；许多." target="_blank">hundred kilohertz. 如果信号频率低于几百kHz，则使用双绞线就已足够。
Clock frequencies up to hundreds of kilohertz might be achievable, but don't look for gigahertz-rated organic chips anytime soon. 或许可以做到几十万赫兹的时脉，但在短期内别想要有10亿赫兹等级的有机晶片。
Any radio waves with frequencies below about one kilohertz (a wavelength of greater than 300 kilometers) cannot penetrate into our galaxy. 我们现在意气风发的要看的更多更远，我们的知识在累积在修正，在通向终极真理，如果它存在的话；
