The formation of vortex was caused by the interaction of two surface stream flowing inwards.

漩涡是由两个相向的表面流相互剪切而形成的。

By the principle of penalt function, the irrotational fluid field is constrained, and author has proposed the Difference Method for distinguishing fluid vortex modes among the natural modes of coupled systems. Author has calculated the real frequencies with the extra deductive method, and discussed the influence of the numerical solution due to the irrotational constraint.

通过台风中心T〓与周边T〓时间序列场同时、滞后相关系数的计算，我们注意到，强迫源的能量频散与台风涡旋的移动确实存在较为显著的相关，且显著相关区的波列特征与台风个例的移动趋势相似。

However, in the Lamaist tradition where there is no difference between the aesthetic and the sacred and where art is always sacred art, the Mandala is a spiritual power vortex, an assembly point of gods and demons, a palace of the divine, a spiritual battery from where powerful energies are radiating. It is also connected with the Lamaist idea that the place, where the Mandala is erected, stands under the absolute control of its divine or, we would say, demonic "inhabitants".

但是在喇嘛教的传统里，审美与神圣并没有区别，曼荼罗被看作是一种灵塔，是神灵与魔鬼的汇聚点，是一种神殿，就象是一种精神电池，从其中可以发出强大的能量，曼荼罗建立之地被认为处于圣灵的绝对控制之下，或者说，在魔鬼的绝对控制之下。
