radio beam
释义
[电子] 射电波束
例句
1·It is far from simply a radio beam passing through a vacuum at "the speed of light".

2·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。
3·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。
