Thank you for sharing

全球競逐深海聲納電波通訊發展🌏🌎🌍

The hunt of Red October 絕對冇Larry 所講的場景。好懷疑渠係冇睇過套戲。

仲有Crimson Tide

[@stevenwu2325]

@@simonwong3831 it doesn’t work that way either. As a US submarine officer reviewed that movie, he said the main sequence would be Hollywood fantasy.

繩索🪢當用詞「偏振」？😳🤔電磁輻射

[@billykwong3525]

點解唔用浮標天綫？當潛艇需要通信時，釋放一個有電線連接住嘅浮標天綫，通信完就把浮標天繞收回，就像船隻拋撈原理一樣，只是上下方向掉轉。浮標天綫體積細效率高隱蔽性强。🤔️

為何不在海底架設環繞地球的電纜，作超低頻電波通訊。

都係覆蓋效益問題，要花好多錢起好多先有效

量子？

可唔可以留返俾陳博士太長氣啦你？
