您要查找的是不是：
- radio beam flying 波束飞行
- 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。
- 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
- A transistorize radio takes no time to warm up. 晶体管收音机不需要预热时间。
- She performed on the balance beam with much grace. 她在平衡木上表演得非常优美。
- Radio Beijing sends the news all over the world. 北京广播电台向全世界播送新闻。
- She petitioned her neighbor to turn down the radio. 她请求邻居把收音机关小点声。
- The beam of the searchlight pierced the darkness. 探照灯的光柱射入黑暗中。
- His answer was right on the beam. 他的答案完全正确。
- They've been plugging his new show on the radio. 他们一直在电台上宣传他的新节目。
- How much do you think this radio will sell for? 你认为这台收音机会卖多少钱？
- I am able to pick you up on the short wave radio. 我能用短波收音机收听到你的信号。
- I was able to pick you up on the short wave radio. 我能用短波收音机收听到你的信号。
