The vortex is the grey ball of smoke shown by the arrow and moving upwards. It is smoke only and is not luminous.

旋涡是灰色球团烟雾所表现出的箭头，向上移动，它是烟雾不仅是不发光。

A short-lived and undoubtedly 'fantastic' stint was brought to an end after The Doctor sacrificed himself, just like his fifth incarnation, to save his companion. Cellular degeneration and regeneration into Barcelona-bound David Tennant ensued once he sucked out and absorbed the Time Vortex from Rose Tyler's mouth. Has anyone else ever found a better pretext for a sloppy snog?

在一句"fantastic"后，博士牺牲了自己，就像他第五个肉身一样，为了拯救他的搭档；从Rose Tyler嘴里吸出时间漩涡能量后，华丽丽地重生为DT版博士；对于这个庸俗伤感的吻，还有谁能找到更好借口吗？

Evidence suggests that when northern snow forced teleconnection is generated in this season, anomalous zonal/meridional circulations are revealed in east Asia-western Pacific band; with east Asia-Pacific teleconnection formed, anomalous zonal circulation is dominant over that band; the anomalous vortex of north Pacific origin moves southwestward and, r...

研究发现当北半球夏季出现积雪强迫型遥相关时，东亚－西太平洋地区既存在异常纬向环流，也存在异常经向环流；而当出现东亚太平洋型遥相关时，东亚－西太平洋地区以异常纬向环流为主。分析还发现源于北太平洋的异常涡旋在向南传播的过程中，先取西南路径，在到达菲律宾东部以后折向东南。

This theory is also applied in the researches of knotlike cosmic strings in early universe and the knotlike vortex lines in spinor Bose-Einstein condensates.

在本文中应用这一纽结理论作者还研究了早期宇宙中的纽结状宇宙弦和旋量玻色-爱因斯坦凝聚体中的纽结状涡旋线。

In addition, the entrainment of the ambient crossflow fluid by the scarf vortex occurs in large part on the surface of the spiral roller structures of itself due to the presence of smaller and unorganized eddies.

此外，由于在其表面存在更小的无组织涡结构，scarf涡与横流流体之间的卷吸作用主要发生在scarf涡的螺旋形条带结构表面。

Results show that there is much local secondary flow in square cyclone besides main vortex, such as spiral down-stream near surface and spiral up-steam at central zone.

结果表明：方形分离器内除外涡旋与内涡旋等主流外，还存在许多局部的二次流，这些二次流是影响分离器的分离效率的主要因素之一；结构参数的变化对二次流的强度及位置产生影响，进而影响分离器的分离效率。

Results show that there is much local secondary flow in square cyclone besides main vortex, such as spiral down-stream near surface and spiral up-steam at central zone. The secondary flow is one of the effect factors on the collection performance of square cyclone. The cyclone geometry size affects on the intensity and the position of the secondary flow, and then affects on the separation efficiency of the cyclone.

结果表明：方形分离器内除外涡旋与内涡旋等主流外，还存在许多局部的二次流，这些二次流是影响分离器的分离效率的主要因素之一；结构参数的变化对二次流的强度及位置产生影响，进而影响分离器的分离效率。

Comparing the unsteady flow fields obtained by CFD with the measurement results with SPIV, it can be found that the CFD results can capture the main characteristics of the flow fields observed in the experiment results, however, the precision of the CFD needs to be further improved, and to predict the detail flow structures, such as the tip leakage vortex in the compressor rotor, by CFD still has some difficulties, thus, some work should be done to improve the turbulence model for more accuracy prediction of the flow fields by CFD for the complex flow in turbomachinery.

定常计算结果和非定常计算结果都不能很好地反映出转子叶尖泄漏流，转子尾迹和泄漏流在静子通道中的演化，及其与静子的相互作用等复杂流动情况。开展叶轮机适用的湍流模型研究，对于提高叶轮机内部复杂流动数值模拟的准确性具有非常重要的价值。
