| 1. | When it swims , its long flowing caudal fins make it look like a fairy dancing gracefully 游动时长鳍飘飘,宛似仙子起舞。 |
| 2. | Looked at from above , its round body and wide spreading caudal fins resemble the chinese character " ? " ( wen ) 从上俯视,鱼体浑圆,尾鳍散开,极像文字,因而得名。 |
| 3. | Among the hundreds of guppy varieties , the best known feature of the male fish is its gorgeous dorsal and caudal fins 在成千上百的孔雀鱼品种中,雄鱼最著名的特色就是它们华丽的背鳍和尾鳍。 |
| 4. | The long and broad caudal fins are curved downwards slightly . it moves gracefully like a phoenix displaying its ornate plumage 尾鳍宽长,微垂向下,泳姿优雅有如凤凰展翅,故名蛋凤或丹凤。 |
| 5. | The study object in this paper is a lunate caudal fin imitating tuna - tail with the mode combined swaying and yawing in uniform flow which is incompressible and inviscid 本文的研究对象是类似于金枪鱼尾鳍的一个推进装置,它是一个月牙形的尾鳍。 |
| 6. | 2 . 40 - red and white swallow - tail belonging to the grass type , the red and white swallow - tail s single caudal fin is long , broad and deeply forked , resembling a swallow s tail 40 -红白燕尾红白燕尾属草种。尾鳍宽长,分叉如燕尾,泳姿曼妙。 |
| 7. | Based on the strategy , this paper gives the equation of caudal oscillating track when the robotic fish swimming forward with a certain speed by using two - link caudal fin 根据以上模型,本文给出了机器鱼在某个时间段匀速下机器鱼两关节尾鳍摆动轨迹方程。 |
| 8. | First , we calculate the hydrodynamic performance of the caudal fin which is considered as a rigid body using surface panel method . then a detailed analysis is given 首先把尾鳍视为刚性体,采用面元法计算其水动力性能,详细分析其水动力系数随尾鳍运动参数的变化规律。 |
| 9. | And explain the correlative parameters and the mechanics of the caudal fin locomotion . the equation of the robotic fish caudal fin locomotion is deduced in the third section 在第三部分,本文分析了鱼类尾鳍推力方程,说明了提高尾鳍摆动的振幅和频率可以提高尾鳍的前向推力。 |
| 10. | This dissertation sets up the kinematics model on the basis of the biomimetic study of lunate - tail propulsion steady swimming fish and of the analysis of fish body motion and caudal fin motion 本文在综合国内外鱼类游动文献中的有关研究成果的基础上,分析了鱼类游动过程中鱼体和尾鳍运动,建立了月牙尾推进模式稳态游动的运动学模型。 |
