  1. The methods will not only make a key tool for noise prediction, but also play a role for noise control of the propeller in engineering project

    整個方法對船舶螺旋槳噪聲預報提供了工具，對螺旋槳的噪聲控制及低噪聲設計也有重要的工程價值。
  2. 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。
  3. Study of low - frequency noise induced by marine propeller

    船舶螺旋槳低頻噪聲研究
  4. The low - frequency discrete noise of the propeller is induced by the interaction between blades of the propeller and wake of the marine, and the low - frequency broadband noise of the propeller is produced by the interaction of blades and turbulent field of the marine stern

    螺旋槳的低頻離散譜噪聲是由船尾伴流場和葉片的相互作用引起的，而低頻寬帶噪聲是由船尾粘性湍流場和葉片的相互作用產生的。
