主要研究内容是探索一种能使减摇鳍在零航速或低航速条件下产生升力的解决方案。
The main content is to explore a scheme that makes fin stabilizers produce lift at zero speed.
对于在低航速或系泊状态下仍需要减摇的船舶来说，传统的减摇鳍就不再适用了。
The traditional fin stabilizers would not be applicable for the ships which still need anti rolling at lower speed or at anchor.
船舶在低航速或零航速情况下，由于流过鳍表面的水流速度为零，鳍上升力也将消失，因而此时减摇鳍几乎不能进行减摇。
The lift of fin would vanish at anchor. Because the speed of water flow across the surface of fin stabilizers is zero on this condition.
