无线电波

The direction that the echoes come from shows the compass bearing of the target.

由目标所反射的无线电波回迹的方向能确认其方位角，电波发射和折返的时间可以确认其距离，每英里需时1.24*10-6 S，目标的仰角可被用以确认其高度。

The direction that theechoes come from shows the compass bearing of the target. The time it takes for the radio pulse to reach the target

由目标所反射的无线电波回迹的方向能确认其方位角，电波发射和折返的时间可

He compared a catalog of 18,000 X-ray sources from the German-American ROSAT satellite, which operated from 1990 to 1999, with catalogs of objects that appear in visible light, infrared light and radio waves.

他对比了伦琴卫星资料列表中的18，000个X射线源。伦琴卫星由德美合作制造，曾于1990年到1999年之间运行，用可见光、红外线和无线电波记录了众多天体的影像。

If we answer that question, it's likely to tell us something new about the environments of pulsars and how their radio waves are generated, she added.

如果我们回答这个问题，它可能会告诉我们一些有关的新的脉冲星的环境，以及如何产生的无线电波，她补充说：。

These sensors need only a very low power consumption, relay to the adoption of radio waves data from one sensor to another sensor, So their communication efficiency is very high.

这些传感器只需要很低的功耗，以接力的方式通过无线电波将数据从一个传感器传到另一个传感器，因此它们的通信效率非常高。

There are several types of pagers but, basically, it's all done by good, old- fashioned radio waves.

有几种类型的寻呼机，但基本上，这一切都做的很好，老式的无线电波。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.
