鳍条

鳍条摆动过程实验测试系统由运动机构及其控制系统、流场显示系统和测力系统组成。

The equipment for the fin ray tests consists of motion control system , digital particle image velocimetry ( DPIV ) system and force measurement system .

这一技术把仿生鳍条结构的优势和Festo自动化尖端技术结合起来。

It combines the advantages of the bionic Fin Ray structure with state-of-the-art automation technology from Festo .

从样品鳍条提取基因组DNA，水平式淀粉凝胶电泳法检测同工酶。

The DNA samples were extracted from the caudal fin ray of samples .

后期仔鱼为器官发育、奇鳍条基本形成期，历时10d，平均全长从4.31mm增至8.97mm。

In the developmental period of post-larvae , which lasts for 10 days , its organ begins to differentiate and fins are basically formed with an average body length from 4.31 mm to 8.79 mm .

同时还进行了鳍条刚度对游动性能影响的对比实验。

In addition , we test the influence of fin stiffness on propulsion performance .

严重时局部坏死、鳞片脱落、鳍条腐烂，蒙眼。

When Severely local body necrosis , shedding scales , fin rotting , blindfolded .

鳍条效应也适用于自动化最基本的实际应用中。

The Fin Ray Effect can also be used in basic practical applications in automation .

有9个分枝的背鳍鳍条；

Has9 branched dorsal rays ;

至18~20日龄，全长7.10~7.31mm时，尾鳍鳍条发育完整。

Then the soft rays of caudal fin developed finally at 18-20 days post hatching with 7.10-7.31 mm whole length .

自鳔一室期至鳍条形成期，以矢耳石来判别时，各期判别成功率分别为63.51%、63.22%、75.31%、91.92%和98.44%。

In five stages from one chamber air bladder stage to formation of fins stage , the discriminant success are 63.51 % , 63.22 % , 75.31 % , 91.92 % and 98.44 % respectively by sagitta ;

海南华鳊侧线鳞少于54，四川华鳊背鳍最末一根不分枝鳍条为弱的硬棘并且吻长小于眼睛，它们是两个有效的物种；

S. affinis and S. taeniatus are two valid species , respectively known from lateral line scales less than 54 and eye diameter longer than snout length , furthermore , the latter 's the last unbranched dorsal-fin ray weakly ossified .

每个“触角”都设计成鱼鳍鳍条结构。

Each tentacle is designed as a structure with Fin Ray Effect .
