  1. Study of low - frequency noise induced by marine propeller

    船舶螺旋槳低頻噪聲研究
  2. Permanent mglev and streamlined propeller with super low noise

    無源磁浮流線型螺旋槳的超靜音研究
  3. 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
