  • fin : n 1 鰭，魚翅；鰭狀物。2 手 臂。3 【航海】（潛水艇的）鰭板，水平舵；【火箭】舵；【航空】穩定器，安...
  • efficiency : n. 1. 功效。2. 效率；效能；實力，能力。3. 【物理學】性能。
  1. From this compare, we can know that the lunate fin has higher efficiency than the rectangle fin

    為研究尾鰭的幾何形狀對水動力性能的影響，本論文選取了矩形翼和月牙形翼進行比較。
  2. 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

    為了使數學模型更貼近生物模型，本文又將尾鰭處理為只考慮弦向變形而不考慮展向變形的柔性體，兩者對比的結果表明，柔性翼使得平均推力減小，但是，對具有相同推力的柔性翼比剛性翼具有更高的效率。
  3. The undulatory dorsal / median fin propulsion modes as represented by amiiform and balistiform fish are of great significance for bionic propulsion research, particularly for the design and control of underwater vehicles, which are generally employed at slow speeds, offering greater maneuverability and better propulsive efficiency

    以弓鰭目和鱗?科魚類為代表的背鰭/背臀鰭波動推進模式對於水下仿生推進器研製具有相當重要的參考價值。
  4. It is shown that the fin efficiency, air flow - rate, and fin performance are significantly decreased while pressure of the air side is increased when frosting occurs at the exchanger

    研究發現，換熱器結霜引起了翅片效率、空氣流通率及翅片性能的顯著降低，同時還伴隨著空氣側壓力降上升。
  5. Study of theoretical fin efficiency of serrated fins with high segment

    高齒段齒形翅片的翅片效率的理論研究
