无线电频率

When radio frequency energy impinges upon your body tissue, part of it is absorbed and converted to heat due to ionic conduction.

当无线电频率能量影响到你身体组织的一部分，它是吸收和转化为热量由于离子传导。

Under the contract, a Lockheed Martin-led industry team will develop three types of expendable communications buoys: two submarine-launched tethered buoys that provide real-time chat, data transfer and e-mail capabilities via either Iridium or UHF satellites; and an untethered, acoustic-to-radio frequency gateway buoy that can be launched from a submarine or maritime patrol aircraft to enable two-way data transfer between a submerged submarine and surface assets.

根据合同，洛克希德马丁公司领导的工业团队将开发三种类型的消耗通信浮标：两个潜艇发射栓浮标提供实时聊天，数据传输和电子邮件功能，通过任何铱星或超高频卫星；和非系留，声学对无线电频率网关浮标，可以从潜艇发射或海上巡逻机，使双向之间的数据传输水下潜艇和水面资产。

A duplexer separates an RF signal received from the built-in dual band antenna from an RF signal to be transmitted to the built-in dual band antenna.

双工器分离从内置双频带天线接收的无线电频率信号和要发送到内置双频带天线的RF信号。

In this thesis, we propose a joint consideration of channel shortening and RFI suppression in the design of time domain equalizers.

在这篇论文里，我们提出同时考虑通道缩短和抑制无线电频率干扰来设计时域等化器。

"This depends on the precise radio frequency of the 21-cm wavelength, or 1420 megacycles per second."

这种通讯依靠的是2l厘米波段(或1420兆周)的精确无线电频率。

Radio frequency identification, or RFID, tags are already changing the way companies keep track of inventory, how owners keep track of pets and how turnpikes collect tolls.

无线电频率识别，或RFID标签已经改变了公司追踪存货，如何跟踪业主的宠物，以及如何turnpikes收集费。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
