鳍

Also has a white or orange-rimmed ocellus on the upper portion of the caudal fin base (sometimes absent or indistinct in indiviuals over 300 mm SL), moderately large scales (LL=52–70), and no scales on the underside of the lower jaw.

也有一个白色或橙低碳易拉丝 ocellus 尾的鳍的上部的 base (有时不存在或模糊 indiviuals SL 超过 300 毫米的)中，大尺度(你= 52–70)，和没有的较低的下巴底面的尺度。

Amongst the more unusual finds were two-meter-long cirrate octopod, an eight-limbed creature nicknamed "Dumbo" because of the large elephant ear-like fins it uses to swim.

其中更加不寻常的是长达两米的触须类八足动物。由于这种动物用来游泳的鳍像大象的耳朵，因此它的昵称叫作"Dumbo"。

Observed ages ranged from age 1 +to 4 +using otoliths and vertebra,1 +to 3 +using opercular.

考虑到暗纹东方生物学的特殊性，其鳞片已经退化成小皮刺；鳍骨柔软、中空，皆不适合用来鉴定年龄。

The characteristics of three kinds of determination materials of Takifugu obscurusAbe,otoliths,vertebra and opercular had been described and compared the similarities and difference and veracity As a result,the otoliths are the best structure of judging age because the annual ring is very evidence and regularity;the vertebra is the better,it is difficulty of measure;the opercular is only the assistant material.

有关暗纹东方养殖生物学和病害的研究已有很多，但对其年龄鉴定却鲜见报道。在整个形目鱼类中仅见绿鳍马面年龄生长的报道，且作为年龄鉴定依据的材料仅限于脊椎骨[1]。

The regression analysis of the hydrodynamic data with the 24 orthogonal series of JDYW models in open water has been carried out, and the estimated formulae of C subscript N(subscript α and C as coefficient of center of pressure are provided, which can be used to design rudder or fin in the vehicle.

JDYW是一种高性能对称翼型，文中对24个正交系列模型敞水流体动力测试数据作了回归分析，给出了C下标 N(下标α和压力中心系数C的估算公式，可供船舵或鳍设计时使用。

5Mm TL. Dorsal and pelic supports appeared by the time the fish reached ca. 3mmand started to ossify at ca.

背腹鳍的支鳍骨出现在鱼达3mm时，而约3.5mm时开始化骨。

For the co-axial flip chip package, we cover a metal lid in the crystal and add a heat sink with basis of 2500 x2500 x1500 . Analysis shows that the package has the optimal heat transfer at the fin's altitude, thickness and spacing of 500, 100 and 166 , respectively, associated with 5 m/s force convection in the test entrance.

在同轴式覆晶外部设计封装上，在金属盖上加上一基底为2500 x2500 x1500 ，鳍片高度、厚度及间距分别为500、100 及166 的热沈；并於测试入口处加入一 5 m/s 的强制对流时，此时封装体拥有最佳的散热效果。

Entrants have to complete two lengths of the course, a 60 yard by 4ft peat bog..

近100名参赛者参加了比赛，他们穿着潜水用的通气管和鳍状肢，跳进了60码长4英尺宽的泥浆池来回游了一次。

Any of several rays of the family Mobulidae,inhabiting tropical and subtropical seas and having a large flattened body,winglike pectoral fin s,a whiplike tail,and two hornlike fin s that project forward from the head.

蝠鲼任一种蝠鲼科的鳐鱼，生活在热带或副热带海域，有大而扁平的身体和翼状的胸鳍，以及鞭状的尾，头的前部有两个角状的向前突出的鳍

Dorsal fin, tail fin and fat fins slightly yellow, pectoral fin, and ventral fin Tunqi gray.

背鳍、脂鳍和尾鳍稍带浅黄色，胸鳍、腹鳍和臀鳍灰白色。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
