查询词典 radio transmitter

The microwave source and vacuum tube amplifier,that is transmitter model,are the core parts of the transmitter.

发射机的功率和频谱质量直接关系着主动雷达导引头的性能，而微波源和电子真空放大器是发射机的核心器件，简称发射模块，其研究开发和装配调试均有相当的难度。

Because the resistance transmitter is built in the tooth gear, when deflexion occurs on the axle of the segment gear, the rocking arm of the resistance transmitter deflects accordingly.

由于电阻发送器系设置在齿轮传动机构上，因此当齿轮传动机构中的扇形齿轮轴产生偏转时，电阻发送器的转臂也相应的地偏转。

YS1 intrinsically safety type pressure transmitter adopts intrinsically safety circuit, suitable for explosive hazardous zone, explosion-proof class ExiaIICT5(explosion-proof certificate no.:CE042114),technical function index is same as standard pressure transmitter.

YS1 本安型压力变送器采用本质安全电路，适用于爆炸危险区域，防爆等级ExiaIICT5(防爆合格证编号：CE042114)，技术性能指标与普通型压力变送器相同。

YS-1-B intrinsically safety type pressure transmitter adopts intrinsically safety circuit, suitable for explosive hazardous zone, explosion-proof class ExiaIICT5(explosion-proof certificate no.: CE042114), echnical function index is same as standard pressure transmitter.

YS-1-B 本安型压力变送器采用本质安全电路，适用于爆炸危险区域，防爆等级 ExiaIICT5(防爆合格证编号： CE042114)，技术性能指标与普通型压力变送器相同。

The transmitter has a physical layer transmitter for receiving data, formatting the received data into packets transmitting the packets and retransmitting packets in response to failure to receive a corresponding acknowledgment for a given packet; an acknowledgment receiver for receiving the corresponding acknowledgment; and an adaptive modulation and coding controller for collecting retransmission statistics and adjusting the particular data encoding/modulation using the collected statistics.

该发射器处的一物理层发射器是接收数据且将该接收到的数据格式化成具有一特殊编码/数据调制的数个分组。该物理层发射器包含n个信道，以发所述分组及相应未接收到相对应一给定分组的一相对应确认信息而再次发送分组。该发射器中的一适应性调制及编码控制器是收集再次发送的统计且使用该收集到的统计来调整该特殊编码/数据调制。该接收器具有一物理层n-信道接收器，以接收所述分组。

Radio telescopes are relatively inexpensive; radio signals travel at the speed of light, faster than which nothing can go; and the use of radio for communication is not a short-sighted or anthropocentric activity.

射电望远镜相对来说是昂贵的，无线电信号以光速行驶，没有什么比起它能走的更快了；而且无线电对于传播的使用不是一种短视或者以人类为宇宙中心的行为。

You may have access to a radio or radio/cassette, or radio cassette/cd player.

您可以使用收音机或收/录音机，或收录机/CD播放器。

All provide a mixture of local news and comment, with some entertainment matter, mainly pop music, in between. In 1991 the Home Secretary appointed a new Radio Authority to take over the functions related to radio of the old IBA, and in particular to grant new licences to broadcast. In the 1990s there should be one or more new commercial radio stations broadcasting nationwide, including one 'non-pop' station, possibly for continuous broadcasts of classical music.

他们既提供地方新闻和评论，还插入一些娱乐节目，其中主要是流行音乐。1991年，内政大臣任命了一个新的广播公司，取代旧英国独立广播管理局的相关功能，尤其是为广播电台颁发新的许可证。20世纪90年代，一个或多个新的商业广播电台在全国范围内应运而生，包括一个"非流行音乐"台，用于长期播放古典音乐。

The theme of this thesis is to study applications of radio communication technologies to direct control of air conditioning load. Other than of Taiwan Power Company self constructed radio load management system, technical feasibility of controlling air conditioners by FM subcarriers of commercial broadcasting stations as well as radio paging system of telecommunication companies are to be studied.

摘要本研究探讨无线电通讯技术於空调负载直接控制之应用，除台电目前既有之无线电负载管理系统，本研究针对租用电信公司无线电传呼系统之无线电传呼式负载管理系统及租用广播公司副载波系统之副载波负载管理系统进行分析与可行性之探讨。

Adopt the generalized maximum likelihood radio test based on the Neyman-Pearson algorithm, to study two unresolved Rayleigh targets. And deduced the detection statistic which is chi-square random variable, which only need to know the conditional probability density functions of echo's measured amplitude, in-phase and quadrature of monopulse radio, but the signal-to-noise radio and the direction-off-arrival of any signal are unnecessary.

采用基于涅曼-皮尔逊准则的广义似然比检测，对不可分辨的两个瑞利目标进行了研究，推出了服从χ2分布的检验统计量，此方法只需要知道目标回波信号测量幅值的条件概率密度函数、单脉冲和差比值的同相和正交部分，而不需要任一目标信号的信噪比和DOA的先验知识。
