翼的

Theoretical analysis of cavitation phenomena around two-dimensional hydrofoils is conducted firstly and cavitation zone profile around NACA 4412 hydrofoil is iteratively solved.

本文首先对二维翼型周围的空化现象进行了理论分析，并迭代求解了NACA4412翼型周围空化区形态。

Pilot was rather experiensed. He had not put the nosecone on and pulled the glider too far.

飞行员有相当的经验，但没套上机头套和拉把手太多，翼面之间充满空气，三角翼开始自动俯冲。

Hold this position with your top wing hand forward and your bottom wing hand slightly back.

保持住这个上翼手靠前且下翼手轻微靠后的位置。

A feather, wing, fin, or similar appendage.

羽、翼或鳍状结构羽、翼、鳍或类似的悬着物

Was mounted in front of the mast on the torque tube, an increase in rotor load would cause a further increase in

如果旋翼安装于桅杆及扭矩管之前，增加的旋翼载荷导致攻角增加，载荷

Rotor wing plane is a new concept of aircraft, and is the combination of rotor aircraft and fixed wing aircraft.

旋转机翼飞机是一种新概念飞行器，是旋翼飞行器和固定翼飞行器的结合。

Wave is the rotor blades hinges on the hinge between the propeller blade hub, the hinge allows the blade perpendicular to the rotor plane up and down waving, in order to make it not have chatter and the shutdown will not touch the ground, usually limited to damping and compatible digital devices ...

挥舞铰是旋翼桨叶于桨桨毂之间的铰接，这个铰接允许桨叶垂直于旋翼平面上下挥舞，为了使之不会产生颤振及在停机时不会触及地面，通常都有阻尼及限位装置相配合。。。。

In the edge roll groove, the top of flange doesnt touch the roll either, the top of f

轧边机孔型中，翼缘的端部也基本不接触轧辊，只是在最后一两道次才对翼缘端部进行加工。

Compared with a delta wing aircraft, the double delta wing configuration has better aerodynamic performance at high angles of attack.

双三角翼气动布局比三角翼飞机具有更好的大攻角空气动力特性。

However, at the touch of a button, telescopic wings emerge from the roof; a rear propeller pops up from the trunk; the "spoiler" becomes a vertical stabilizer that extends up over the car; and, finally, a pair of horizontal stabilizers appear from just behind the rear wheels.

不过，只需轻摁按钮即可弹出伸缩机翼；后面的螺旋桨从车厢来出现；&扰流器&变成垂直稳定翼，延伸至整个汽车；最终，两个水平稳定翼会从后轮后面现身。

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。
