But combining radio waves also makes for less sharp, lower resolution images.

但混合无线电波也会降低图像的清晰度以及分辨率。

As another example, cosmic rays have a wavelength of lessthan a millionth of a millionth of an inch, while some radio waves have wave lengths of over a mile!

再举另外一个例子，宇宙射线的波长不及万亿亿分之一英寸，而某些无线电波的波长却超过一英里！

You turn on your radio, the radio waves passing by, boom, properly tuned, you detected it.

你打开收音机，无线电波传出来，好好地调试一下，你就检测到它了。

That is not to say that radio waves cannot pack a punch from a distance.

这并不是说无线电波不能保存来自远处的力量。

It can detect the presence of people on the other side of a barrier by distortions to the reflected radio waves caused by their breathing or heartbeat.

它可以通过由人们呼吸和心跳所引发的，反射无线电波产生的扭曲，来探测障碍的另一边是否有人存在。

Near some sprites, the team also found radio waves in 310-mile-wide (500-kilometer-wide) bands-and these radio waves were most likely being emitted by high-speed particle beams.

该小组还在一些气辉周围发现了310英里(500公里)波段的无线电波。这些无线电波很有可能就是由高速粒子束发出的。

Now the galaxy is full of gas and dust, which could hide a distant supernova optically, but the remnant would still produce detectable radio waves and X-rays.

现在，星系充满了气体和灰尘，掩盖了遥远的超新星的可见性，但是(它的)残骸依然放射出可检测的无线电波和X射线。

But the attraction of radio waves is that they are pretty much everywhere.

但是无线电波的吸引力在于它们几乎无处不在。

The Atacama Large Millimeter/submillimeter Array (ALMA) will look just at the under-studied shortest radio waves of the universe by combining signals from a field of 66 separate dish antennae.

阿卡塔玛大型毫米及次毫米波数组(ALMA)将混合从66个独立的碟面天线得到的信号，专注于宇宙超短无线电波的研究。

Ambient radio waves have largely been ignored as a potential power source until recently, because the power of a broadcast radio signal rapidly decreases with distance.

直到最近环境无线电波才格外受到重视成为一种潜在的电源，这是因为广播电台的无线电信号发电随着距离的增加而锐减。

By now an idea obsessed him: that directed radio waves could be used to heat and destroy cancer cells.

一个念头一直缠绕在他的脑海里：导控无线电波也许可以用来加热并破坏癌细胞。

The cheapest way to increase capacity is to add more spectrum or to move a network to a lower frequency, which allows radio waves to penetrate walls more easily.

提高带宽容量最便宜的方法是增加更多频谱或是某个网络降低到更低的频率以使无线电波更容易穿透墻壁。

Mobile phones communicate by transmitting radio waves through a network of fixed antennas called base stations.

移动电话通信通过一个称为基站的固定天线网络发射无线电波。

Arrays of radio telescopes combine the radio waves they collect to vastly enhance the resolution of their cosmic images.

射电望远镜阵列混合了它所收集的无线电波，极大的提高了宇宙呈像的分辨率。

The satellite would then convert the energy into radio waves and beam them down to a receiving station on Earth.

卫星将空间太阳能产生的电能转化成无线电波，传送到地面接收站。
