Time the beam right and the star could be turned, in effect, into an FM transmitter-broadcasting to the universe on the underlying carrier-wave of the Cepheid's pulsation.
只要恰当地控制粒子束的照射时间，该恒星将有效地成为一台调频电台——以“造父变星”的脉冲为基础载波向宇宙广播。
The number of people listening to short-wave radios has been dropping fast, while a growing number now listen online or via local FM re-transmissions.
收听短波电台的听众人数急剧下降，相反在线收听或者通过当地调频接受的用户不断增加。
Thus FM radio at relatively high frequencies is used for local stations but does not travel far, whereas short-wave radio, at low frequencies, can stretch around the world.
因此地方无线电台使用频率相对较高调频无线通讯，而低频短波无线电则可以遍及全球。
There is a growing interest in the frequency modulated continuous wave (FM-CW) SAR for its advantages such as small cubage, light weight, cost-effective and high resolution.
调频连续波(FM -CW)合成孔径雷达因其体积小、重量轻、成本低及分辨率高等特点越来越受到关注。
As a result, a single radio wave from an FM station is only a few meters long, about the size of a car.
所以，一个单独的电波信号从FM电台里出来，对车而言就是几米的距离。
As a result, a single radio wave from an FM station is only a few meters long, about the size of a car. An AM station is putting out radio waves that are hundreds of times as long!
所以呢，一条单一的调频波段只有几米长，差不多就一辆车的大小。中波波段比调频波段长几百米呢！
One can hear English 24 hours a day by listening to short-wave radio or FM stations that broadcast music and information shows in English.
首先，中国国内几乎到处都有英语：短波和调频台一天24小时都在播放用英语主持的音乐节目及其他知识性节目；
As a result, a single radio wave from an FM station is only a few meters long, about the size of a car.
因此，调频广播电台发出的一个电波的长度只有几米，大概是一辆车的大小。
In frequently used methods, sine wave is used as carrier with amplitude modulation (am), frequency modulation (FM) and phase modulation (PM) implied.
常用的调制方式使用正弦波作为载波并对其进行幅度调制(AM)和角度调制即调频(FM)或调相(PM)。
Time the beam right and the star could be turned, in effect, into an FM transmitter—broadcasting to the universe on the underlying carrier-wave of the Cepheid's pulsation.
精确调制中微子束实际上能够将这些恒星变成FM发射器，使用造父变星的脉冲作为基础载波对整个宇宙进行广播。
Time the beam right and the star could be turned, in effect, into an FM transmitter—broadcasting to the universe on the underlying carrier-wave of the Cepheid's pulsation.
精确调制中微子束实际上能够将这些恒星变成FM发射器，使用造父变星的脉冲作为基础载波对整个宇宙进行广播。
