These components are known as the zonal kinetic energy and eddy kinetic energy respectively.

这两部分能量分别称作纬向动能和涡旋动能。

Namely, the fluid of swift water and tiny whirlpool come from kinetics of the process which make the mass transfer better; 2 Increase alkalinity to improve the capability of abirritation of the system and an optimal pH condition which fit to acidic bacterium come into being.

即通过动力学措施造成反应器内流体介质的湍动及形成微涡旋，利用涡流扩散和对流扩散来加速传质；2提高所处理的碱度，增强系统的缓冲能力，控制酸化菌生存的最佳pH值范围，以实现系统在酸化段有机去除能力的高效性。

By using CFD method, it was available to get not only the distribution of pressure, velocity and eddy air, but also the aerostatic force coefficients of a box girder section.

用计算流体力学方法模拟了桥梁跨中断面周围的风场特征，不仅能得到流场的压力、速度和涡旋的分布，还提取了箱梁断面的三分力系数。

Then we present our studies on several novel quantum phenomena in the rotating and molecular BECs. In the averaged vortex approximation, a fast rotating BEC in an anharmonic potential is studied in variational method.

研究结果很好地解释了实验中所呈现出的许多令人迷惑的新奇现象；同时，证明了在非简谐振子势下，快速旋转的BEC中能够形成带多个单位角动量的涡旋。

The azimuthally linear advection may results in that the meso-scale vortex of initially circular shape becomes the elongated and spiral vorticity bands; the radial linear advection may transfer the vorticity of the outer region towards the center of the typhoon.

沿e方向的线性平流可使初始圆形的中尺度涡旋演变为狭长的螺旋状的涡量带；沿径向线性平流的引进可使外区涡量向台风中心方向传播。

The introduction of nonlinear advection into the model weakens the intensifying of maximum tangential wind with relative to the initial disturbance azimuthally wave numbers and intensity .2 An f-plane quasi-geostrophic barotropic vorticity equation model of high resolution is designed in this paper in order to investigate the characters of vorticity propagation and the effect of nonlinearity on the propagation within a typhoon circulation, wherein two mesoscale vortices coexist at different radial positions.

设计了一个高分辨率的f平面的准地转正压涡度方程模式，用以研究两个径向距离不等的中尺度涡旋共存条件下，台风环流内涡量传播的特征，以及非线性在此传播过程中的作用。10组试验的结果指出：与单涡条件相比，涡量内传的强度显著加强，涡量滞留在台风内区的时间加长，内区局域最大风速增大的现象更加清楚。

Light from an aurora borealis swirls over Yellowknife, the capital of Canada's Northwest Territories.

光从北极黎明的女神涡旋形越过耶洛奈夫，它是加拿大的西北地区的首都。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
