无线电波

Now a team led by Neal Patwari and Joey Wilson of the University of Utah has come up with a way to peer through the walls of a building using a network of little radios that cost only a few dollars each

威尔逊带领的来自犹他大学的一个小组已经研究出一种低价的透视墙的方法。他们用的是微型无线电波网络，成本只有几美元而已。

In one experiment, for example, a network of 34 radios was able to keep track of Mr Wilson's position with an accuracy of less than a metre—a figure that Dr Patwari and Mr Wilson think could be improved greatly by using specially designed radios instead of off-the-shelf ones.

帕特瓦瑞博士和威尔逊先生认为他们还可以使用专业设计的无线电波取代现成产品，那么其准确率还可以提高。

German hertz discovered radio wave and after invention of Italian Ma Keni is subsequently radiotelegraphic, radio communication technology passes the development of a many century, fetched spectacular gain.

梗概： 德国人赫兹发现了无线电波以及随后意大利人马可尼发明无线电报之后，无线电通信技术经过一个多世纪的发展，取得了惊人的成果。

The squares mark the locations of the signal candidates revisited during the reobservation sessions.

但是这神秘的无线电波已经使全世界的天文学家无比兴奋。

The nuclear energy isreleased attheSun'scenter as high-energygammaradiation, aformofelectromagnetic radiationlike lightandradiowaves, only of very much shorter wavelength.

核能在太阳的核心被释放为高能的伽马射线。这是一种电磁射线，就象光波和无线电波一样，只是波长要短得多。

The invention solves the problem of accessing to network by using infrared or low power laser light communication in subrange, especially aims at multi users on-line by optical signal in room place and being liable to interference with WLAN build with conventional air wave transmission. The optical accessing LAN consists of an accessing point and multi users devices.

本发明涉及局域网通信技术领域，公开了一种光接入局域网系统，能够解决局部范围内以红外线或低功率激光的光通讯方式上网的问题，特别是针对室内空间多用户以光信号传输方式上网的情况，以及解决以传统无线电波传输方式组建WLAN的易受干扰信息安全问题。

Violette Impellizzeri, formerly of the Max Planck Institute and now with the National Radio Observatory in Virginia, led the investigation of the ancient water disc.

前卜朗克无线电波天文研究院的因帕乐丽，现在维吉尼亚国家无线电天文台，领导古代盘状水调查。

His calculations suggested that using lasers to ionise molecules of carbon dioxide, and radio waves to get them to spin at the correct rate, would cause those molecules to spiral away from Earth along the lines of magnetic force until they were lost for ever in space.

根据王的推测，使用镭射将二氧化碳分子电离，利用无线电波使其以精确的比率旋转，这样就可以使那些分子沿着磁力线从地球上急速旋转出去，直到永远地消失在宇宙里。

This involves bombarding an object with radio waves.

这种方法涉及用无线电波引爆物体的过程。

A Soviet device that bombards brains with low-frequency radio waves may be a replacement for tranquilizers and their unwanted side effects, says a researcher, but it's use on humans poses ethical and political questions.

一个苏联的装置，它能用低频攻击大脑。无线电波也许是镇静品的代替并减少其副作用，研究者说到，但它被用于人体造成了道德和政治问题。

In the United States, chronic alcoholism and hepatitis C are the most common ones.

在美国，慢性酒精中毒，肝炎是最常见的。
