而且有一群强大的银河系外微波和无线电源，弄脏了我们的图片！
But a bunch of strong extragalactic microwave - and radio-sources are out there too, mucking up our picture!
仙后座a首先在1947年被作为无线电源而探测到。奇怪的是，当时几乎没人注意到它。
Oddly, no one seems to have noticed it at the time and it was first detected in 1947 as a radio source.
大约125前，尼古拉。特斯拉进行了最早的无线电源实验，如今，无线电源技术正在成为当下电子设备最主流的特征。
Some 125 years after Nikola Tesla conducted the earliest experiments, wireless power is on the road to becoming a mainstream feature of today's electronic devices.
首先就是无线电源协会于2008年12月成立。 该协会致力于建立一个统一的无线充电行业标准，并推动其实践应用。
The first is the formation in December 2008 of the Wireless Power Consortium, a body dedicated to establishing a common standard for inductive wireless charging, and thus promoting its adoption.
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。
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.
这颗卫星上装有无线电收发设备和电源，可对信号接收、处理、放大后再发射，从而大大提高了通信质量。
Telstar is launched as the first "active" communications satellite—active as in amplifying and retransmitting incoming signals, rather than passively bouncing them back to Earth.
无线电、无线电耳机及数字通信设备也将包括在内，还包括计算运行所需的电源和软件。
Radios and a headset for audio and digital communication will also be included, along with the power source and software needed to run the Army’s computer applications.
来自Glasgow大学的DuncanGregory教授说：“步兵需要用于武器、无线电、全球定位系统以及很多其他设备的重要部分所需的电源。”
Professor Duncan Gregory, from the University of Glasgow, said: 'Infantry need electricity for weapons, radios, global positioning systems and many other vital pieces of equipment.
一家生产无线电力系统的美国公司Witricity公司的首席执行官埃里克·贾尔说，这一技术最终将代替电池作为便携的电源。
Eric Giler, chief executive of Witricity, a US firm building wireless electricity systems, said that the technology could eventually replace batteries as well as conventional power sources.
该装置可以成为一种“切断开关”，如果检测到无线电数据传送，在用户试图将手机关闭后，它就会断开手机的电源。
It could be developed to act as a sort of "kill switch" that would disconnect a phone's power supply when it detects that a radio is transmitting data after its owner has attempted to turn it off.
传感器单元无电源供电，传感的能量来自外界的无线电磁波。
The energy of sensing comes from external radio electromagnetic wave.
然而，通常意义下无线电能传输技术只能以“点对点”模式实现电源对受电设备的直接供电。
However, classic wireless power transfer technology can only resort to "Point to Point" mode to realize direct power supply form power source to load.
