He ' s very impressed by himself ever since he got a buggy - whip 自从他装了长无线电天线后,非常沾沾自喜。
Steel radio towers and masts 钢质无线电天线塔和天线杆
One solution to this problem lies in a new class of radio antennas that could dramatically reduce man - made interference 有一类新型的无线电天线可大幅减轻人为干扰,或许能解决这个问题。
A radio antenna converts electric currents and voltages created by a transmitter into electromagnetic waves that radiate into space 无线电天线会把发射器产生的电流与电压转变成电磁波,然后以辐射方式在空中传播。
The teams set up their control centres by the pit wall : high - tech tents with computers , monitors and radio antennae 车队将他们的指挥中心设立在维修站的护墙边:在这个高科技的帐篷中有计算机、监视器和无线电天线。
Associated with three research projects , this work is mainly concerned with array elements , array structure and calculations of array impedances versus operating frequencies . in the dissertation , the author ' s major contributions are as follows : a new types of array structure , known as circular reflection array , is proposed and studied . a detailed analysis to the new structure with two cases is presented 本文紧密结合“十五”国防预研“软件无线电天线”和海军预研“智能天线在舰艇上的应用”及“机载微带天线”等项目,着重对智能天线阵列的阵列单元、阵列结构、阵列阻抗的频率特性计算等技术进行了分析和研究,所取得的主要成果如下: 1
Two or three water towers , the backs of two or three steel frames for billboards , perhaps a spire or two , and a stretch of asphalt roofing material and bricks going up in square , sharp , vertical outlines without any form or order , sprinkled with some dirty , discolored chimneys and a few washlines and crisscross lines of radio aerials 两三座水塔,两三个钉广告牌的铜架,一两座尖塔,一望相连的沥青的屋顶材料和砖头,形成一些四方形的、矗立的、垂直的轮廓,完全没有什么组织或次序,点缀着一些泥土,退色的烟突,以及几条晒着衣服的绳索和交叉着的无线电天线。
