From this compare , we can know that the lunate fin has higher efficiency than the rectangle fin 为研究尾鳍的几何形状对水动力性能的影响，本论文选取了矩形翼和月牙形翼进行比较。

In order to imitate tune tail fin better , a flexible fin only in chordwise is considered . results shows that flexibility can increase the propulsive efficiency and cause small decreases in the average thrust compared with a rigid caudal fin with similar motion . next , a comparison between the rectangle fin and the lunate fin is given 为了使数学模型更贴近生物模型，本文又将尾鳍处理为只考虑弦向变形而不考虑展向变形的柔性体，两者对比的结果表明，柔性翼使得平均推力减小，但是，对具有相同推力的柔性翼比刚性翼具有更高的效率。
