  1. Moreover, addition movement of the airframe can result from aerodynamic or propulsion noise.

    此外氣動力或發動機擾動也會造成彈體的附加運動。
  2. Compared with dc - mhd propulsion, ac mode has no electrode and does n ' t apply electric field to fluid directly. thus it avoids the detriment and noise caused by the air bubble generated by electrolysis, and makes the ship more quietly. these characters will help to develop a more efficient ship thruster

    與直流磁流體推進相比,交流磁流體推進方式的最大特點就是沒有電極,因此沒有電極壽命問題,消除了電極表面壓降對推進器效率的影響,也沒有電機表面電化學過程產生的不良效應,如氣泡、電解質對海水的污染等。
  3. Fish and ocean mammal have excellent propulsion and maneuvering system, whose advantages are high efficiency and low noise

    魚類和海洋哺乳動物有良好的推進系統和操縱系統,其突出的優點是效率高、噪聲低。
