Furthermore, Ptychidio distinctly differed in osteological characters from other genera of Labeoninae, so it wasn't chosen as taxon of ingroup in phylogeny of Labeoninae. And Ptychidio's phylogenetic status can be ascertained only if more taxons of Cyprinidae be chosen and phylogeny of Cyprininae be solved in further research and molecular research.

此外，在特征分析时发现，卷口鱼属同野鲮亚科其它属的骨骼特征相差甚远，所以在分支系统学分析时没有被选择，有关其分类地位的确立，有待于今后在鲤科分支系统学研究中和分子生物学资料的研究中解决。

This paper takes the small fish of Carangiform as the mimetic object. Through the bionics study to the principle of Carangiform"s propulsion, the robofish"s main body mechanism that has two degrees of freedom tail fin and single degree of freedom pectoral fin has designed. At the same time, the parameterized mathematical model of double-hinged propulsion system has established. The kinematics analysis, dynamics analysis to the propulsion process and preliminary hydrodynamics analysis to the tail fin and the pectoral fin have been completed. The dynamic equations to the propulsion system have been established.

本文以鲹科模式鱼类为仿生对象，通过对鲹科模式鱼类游动机理的仿生学研究，设计了两自由度的尾鳍推进机构及单自由度的胸鳍机构的机器鱼机械本体结构，建立了参数化的两关节尾鳍推进模式的数学模型，并对推进过程进行了运动学、动力学分析，建立了推进系统动力学方程，对尾鳍和胸鳍推进的水动力进行了初步分析。

Bryant said he hasn't spoken with Derek Fisher since Monday, when Fisher was released by the Utah Jazz so he can concentrate on finding the best care for his 11-month-old daughter, who has cancer in her left eye.

科比说他还没有与小鱼谈话，在星期一小鱼与爵士解除了合同，这样他可以集中精力为他11个月大左眼有毒癌的女儿找一个更好的治疗。

Using engineering and numerical analysis software Matlab some simulations of the model are carried out, and the motion simulations of the fish body and the caudal fin under different kinematics parameters are also carried out.

根据对鲹科加新月形尾鳍推进模式的仿生学研究，在分析游动过程中身体与尾鳍运动的基础上，建立了一维稳态游动情况下鱼体及尾鳍的运动学模型，利用Matlab工程分析与计算软件对该模型进行了运动仿真，并进行了尾鳍和鱼体在不同运动参数下的仿真研究，给出了适合仿鱼水下推进器设计的参数取值范围。
