coded radio beam 编码无线电波束
The radio beam came from outer space. 这个无线电波束来自外太空。
Like the searchlight beam, the radio beam cannot be made very sharp; it tends to spread. 无线电射束也象探照灯的光束一样，是不能高度集中的；它总要散开。
Ironically, the detailed reasons as to how the radio beam is produced may not be important astronomically. 具有讽刺意义的是,产生射电波束的详细原因在天文上,这也许并不重要。
And the spacecraft's antenna will receive a powerful radio beam from Earth passing through Pluto's atmosphere. 来自地球的强大无线电波能穿透冥王星大气层，为太空船的天线所接收。
The transmitter stays put,with its radio beam pointing in the direction we wish to explore,and the sail travels along the beam,picking up momentum from the radio saves. 发射器固定不动，它的无线电波指向我们希望深测的方向；探测器沿着电波的方向运动，从无线电波获取动力。
The generating of pseudo random sequence is one of the key subjects to realize the spread spectrum technique upgrade for BPC low frequency time code radio station. 伪随机序列的产生是实现BPC低频时码发播台扩展频谱技术升级的一个重要环节。
It is much easier to steer the radio beams electronically. 以电子方式控制无线电波束，会简单许多。
And when the array transmits back to the cell-phone user, the processor sends an out-of-phase signal to one of the antennas, generating a radio beam that runs from north to south. 当阵列发射讯号给行动电话用户时，处理器会传送一个异相的讯号到其中一个天线，产生由北往南的无线电波束。
The transmitter stays put, with its radio beam pointing in the direction we wish to explore, and the sail travels along the beam, picking up momentum from the radio saves. 发射器固定不动，它的无线电波指向我们希望深测的方向；探测器沿着电波的方向运动，从无线电波获取动力。
A radio beam. 无线电波
The coded message was indecipherable. 这份用密码写的消息译不出来。
Sorry. I must have got the wrong area code. 对不起，我一定是拔错地区号码了。
The highway code is not itself part of English law. 公路法规本身并非是英国法的一部分。

She tapped out in code to headquarters. 她给总部发出密码电报。
Self-focusing and defocusing of narrow radio beam in lower ionosphere 无线电窄波束在低电离层中的聚焦和散焦
But the code does not disturb the profits. 但这种审查法规既不影响影片的利润。
Please stamp the code numbers on. 请把代号上或打上。
