For example, very low frequency radio waves can be detected with a special type of radio receiver called a very low frequency radio or VLF radio, which can pick up radio waves with very low frequencies, from 3 to 30 kilohertz, which aren't really picked up by a regular household or car radio.
比如，低频无线电波可以通过无线电接收器来接收。这个接收器叫做低频无线电或VLF无线电。可以接收3到30千赫兹的无线电。这个范围是家庭无线电和汽车无线电不能够接收到的。
