  3. Western union installs the first commercial radio beam system

    西部聯合電報公司安裝第一個商用無線電波束系統。
  4. Like the searchlight beam, the radio beam cannot be made very sharp; it tends to spread.

    無線電射束也象探照燈的光束一樣，是不能高度集中的；它總要散開。
  5. Ironically, the detailed reasons as to how the radio beam is produced may not be important astronomically.

    具有諷刺意義的是，產生射電波束的詳細原因在天文上，這也許並不重要。
  6. Coded radio beam

    編碼無線電波束
  7. Instead of generating a radio beam, the array creates a “ personal cell ” that can be only centimeters in radius

    這種陣列不再製造無線電波束，而是產生半徑只有數公分大的個人單元。
  8. Notice that in both these examples the radio beam generated for one cell - phone user does not reach the other

    注意，在上述兩例中，針對其中一名用戶產生的無線電波束，並不會抵達另一位用戶的所在位置。
  9. An antenna array that is truly smart would be able to aim a radio beam directly at a mobile user instead of choosing a beam that comes relatively close

    一個真正聰明的陣列天線，必須能夠直接把波束瞄準行動用戶，而不是選用與用戶較為接近的波束。
  10. 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

    當陣列發射訊號給行動電話用戶時，處理器會傳送一個異相的訊號到其中一個天線，產生由北往南的無線電波束。
  11. Because the processor is fast enough to perform this task many times a second, the array can continually readjust the radio beam as the cell - phone user walks or drives across the array ' s coverage area

    因為處理器的速度很快，可在一秒內執行多次工作，所以當行動電話用戶在陣列涵蓋?圍內行走或開車時，陣列可不斷重新調整無線電波束。
  12. The multi - beam receiver is also uniquely suited for resolving one of the nagging problems of modern radio - telescopy : screening out radio frequency interference ( rfi )

    多波束接收器也是唯一適合解決現代射電望遠鏡的一個通病：濾掉電波干擾。
  13. She passed away due to prolonged exposure to radio - beam leading to leukaemia

    居里夫人最後因為接觸太多的化學品和無線電波，得到白血球血癌癥。
  14. In layman ' s terms, serendip could find the radio - wave equivalent of a powerful lighthouse beam anywhere along a foggy coast

    用外行的話說， serendip可能發現的無線電波相當于霧茫茫的海岸上大功率燈塔的光芒。
  15. Tuning for radio - beam

    定向接收調諧
  16. Unlike ordinary radio telescope receivers, which point and listen to a single point in the sky at any given time, arecibo ' s new multi - beam receiver can point to seven different points simultaneously

    與普通的射電望遠鏡接收器在一個給定的時間只能指向並監聽天空中的一個點不同，阿雷西博的新多波束接收機能同時指向7個不同的方向。
