The cover member and the retainer collectively define a ribbon cable receiving area and the mating surfaces on the cover member and the retainer have indentations that urge the conductors of the ribbon cable so as to center the conductors in a conductor space defined by the indentations.

外壳及护圈共同定义一带状缆线接纳区域，外壳与护圈的配合表面均有刻痕，使在带状缆线的导体在由刻痕所定义的导体空间内对中。

In this review placoid scale's structure, shapes and the drag-reduction function of its riblet surfaces are introduced.

这种沟槽形态的鲨鱼盾鳞肋条结构具有良好的减阻作用。

Investigation into the drag-reduction mechanism of riblet surfaces makes placoid scale a perfect object to biomaterial research.

鲨鱼体表覆有一层细小的盾鳞，盾鳞上的脊状突起称为肋条，肋条之间构成具圆弧底的沟槽。

Next to the possibility of combining resistance-lowering riblet surfaces with the lotus effect for use on aircraft, it has been demonstrated in water that an artificial shark skin made of elastic material significantly delays biofouling, i. e. the growth of marine microorganisms on a surface.

旁边 riblet 表面电阻降结合使用 Lotus 影响，在飞机上可能它已被证明水中大弹性材料制成的人工鲨鱼皮肤延迟附著，岛·生长的表面上的海洋微生物。

The mean velocity distributions in turbulent boundary layers of smooth surface and two different riblet surfaces are measured with IFA300 constant-temperature anemometer in low-speed wind tunnel to validate the full development of turbulent boundary laye. Friction velocity and wall friction stress of turbulent boundary layer are obtained with the least-squares fitted curve of the sublayer velocity distribution based on Spalding formula, and virtual origin position of riblet surface can be acquired accurately.

在低速风洞中来流速度一定的情况下使用IFA300恒温热线风速仪测量了光滑表面和两种不同尺寸的脊状表面湍流边界层平均速度分布剖面，并验证了试验段湍流发展的充分性；通过应用Spalding壁面公式使用最小二乘法精准拟合了实验测量的边界层内层速度分布曲线，得到了湍流边界层壁面摩擦速度并进一步求得湍流壁面摩擦应力，较准确地计算出脊状表面的虚拟原点位置，并通过与对数律公式拟合结果比较分析，证实了该方法更加准确有效。

The characteristic expression of multi-value function by using Riemann surfaces is discussed, and the mapping from s-plane into w-plane is also analyzed. Then the relations between pole distribution of fractional-order systems and time-domain response are provided.
