In the vortex ring gait, the upstroke is aerodynamically passive (there is no bound circulation during this phase, and hence no trailing vortex), and the wings flex and move close to the body to minimize drag.

在涡环的步态， upstroke是aerodynamically被动的（是没有约束，流通在这一阶段，因此没有尾随涡），和翅膀flex和动议接近身体，以减少阻力。

The results do indicate that there may be several mechanisms for asymmetric vortical flow.

本文结果表明了大迎角旋转体非对称涡的形成机理可能是多种的，即给定分离线位置不对称或自由涡线的个别线段不对称都能产生非对称涡流。

The diffusion of vorticity in the boundary is balanced by the tilting of planetary vorticity.

边界层中涡度的扩散与行星涡度的倾斜平衡。

Plateau vortices are the typical system of positive vorticity.

高原涡是高原正涡度中心的一种典型系统。

Furthermore, the relationship between the vorticity, especially on the cylinder surface, and the disturbance is derived and explained theoretically.

进一步推导并理论解释了涡量，特别是表面涡量，和扰动之间的关系。

Despite differences in wing shape and wing loading, both species shifted from a vortex-ring to a continuous-vortex gait at a speed of 7 meters/sec.

尽管有分歧，在机翼形状和翼载荷，无论是物种的转移，从涡环一个连续涡步态在速度7米/秒。

The winglet type of vortex generators used in elliptic tube exhibit the best performances of area reduction rate at higher velocity applications.

矩形翼对波浪型涡漩产生器的热传性能较低於环状波浪型涡漩产生器，压降也较高，不过由於热传性能提升的幅度较压降增加率高，故面积缩率能随著流速的增加而提高。

This turbulence includes various components, the most important of which are wingtip vortices and jetwash.

这动荡包括各组成部分，其中最重要的是翼梢涡和尾涡。

Wingtip vortices make up the primary and most dangerous component of wake turbulence.

翼梢涡弥补的首要和最危险的部分尾涡。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
