潛艇聲納 的英文怎麼說
中文拼音 [qiántǐngshēngnà]
潛艇聲納
英文
submarine sonar-
The submarine noise detected by sonar consists of two parts : propeller - generated hydro - dynamical noise, which can be greatly reduced by improving the submarine rear shape ; radiated noise from the submarine structure excited by the centrifugal forces ( moments ) of rotatory machine, which is more complicated and influenced by many factors
聲納所探測的潛艇噪聲包括兩部分，一是螺旋槳運轉帶來的水動力噪聲，二是潛艇主機工作時產生的不平衡力和力矩引起潛艇結構振動，帶動流場振動從而輻射噪聲。通過改進潛艇尾部線型設計，已將水動力噪聲降到比較低的程度，而結構噪聲則復雜得多，與許多因素有關。In civil engineering applications, for example harbor - constructing and bridge - building, need information of sea bottom. in military engineering applications, identification of sea bottom types are vary important for match field location, low - frequency sonar distance forecast, and choosing the location for submarine
