查询词典 vortex

The low-dimensional Galerkin method is generalized to solve the flow around arbi-trarily translating circular cylinder.Active control problems of wakes behind circularcylinders are numerically investigated by only small number of modes.The in-line andtransverse oscillation of a circular cylinder with proper frequency produce Karman vor-tex street successfully in some subcritical regime,vhereas the transverse oscillation of acircular cylinder with 1.8 times the natural shedding frequency can effectively suppressthe Karman vortex street at a slightly supercritical Re.

将低维Galerkin方法推广至可以求解任意平移运动圆柱的绕流问题，用较少的模数值研究了圆柱尾迹的主动控制问题，在亚临界Re数下圆柱以适当的频率沿流向和横向振动均成功地激发出Karman涡街；而在略高于临界Re数下圆柱以1.8倍自然脱涡频率沿横向振动明显地抑制了Karman涡街；再现了超临界Re数横向及流向振动圆柱绕流的频率锁定等复杂非线性现象。

Consider a circular vortex ring of radius R.

考虑半径为R的涡旋环。

Therefore if thou shalt separate from thyself, that is, from thy understanding, whatever others do or say, and whatever thou hast done or said thyself, and whatever future things trouble thee because they may happen, and whatever in the body which envelops thee or in the breath, which is by nature associated with the body, is attached to thee independent of thy will, and whatever the external circumfluent vortex whirls round, so that the intellectual power exempt from the things of fate can live pure and free by itself, doing what is just and accepting what happens and saying the truth: if thou wilt separate, I say, from this ruling faculty the things which are attached to it by the impressions of sense, and the things of time to come and of time that is past, and wilt make thyself like Empedocles' sphere

因此，如果你是自己，也就是说使你的理智同这些事情分开－即不管别人做或说了什么，不管你自己做或说了什么，不管将来可能发生什么事情使你苦恼，不管在将你包裹的身体中，或者在天生与身体结合在一起的呼吸中，有什么东西违背你的意志而附着于你，不管那外部缠绕的事物旋涡是如何旋转，为了使免除了命运束缚的理智力自身能纯粹和自由地活动，那么去做正当的事，接受发生的事和诵出真理吧，我说，如果你使这种支配能力脱离开那些通过感官印象而附着于它的事物，脱离开那些未来的和过去的事物，你就将使自己像恩培多克勒的球体一样

If the circumpolar vortex lasts longer than usual in future years, a large ozone hole could be expected to develop above the Arctic.

如果环极涡旋在未来几年里比正常情况下持续更长时间，一个大规模的臭氧空洞就很可能在北极上空发展起来。

With random disturbances on the inlet of the jet, axisymmetric instability appears firstly and then the large coherent structure—vortex ring is formed.

在模拟自然射流的随机扰动的条件下，射流首先出现轴对称失稳，形成大尺度拟序结构一涡环。

How it works: The Mileage Maxx produces a vortex, effect in the combustion chamber of your engine.

它是如何运作的：里程maxx产生旋涡，影响燃烧室的你的引擎。

In chapter 4, employing the molecular dynamics simulations, we study the melt-ing transitions in driven vortex lattices with commensurability between arrays ofvortices and defects.

在第四章中，采用分子动力学模拟，研究了在涡旋与钉扎缺陷之间匹配条件下的驱动涡旋晶格的融熔转变。

By mean of the method of upper and lower solutions, we will obtain a existence theorem like Kazdan-Warners. Using this theorem, we will study the vortex equation in holomorphic line bundle over complex manifold and prove a theorem of existence of Hermitian metric with a prescribed holomorphic section.

在本论文的最后部分，我们在紧复流形上讨论一类Kazdan-Warner型方程，用上下解方法得到了光滑解存在的Kazdan-Warner型定理，并将其用于研究全纯线丛的涡旋方程，得到了一个具有预定全纯截面的厄米度量的存在定理。

Honda defied conventional wisdom by announcing that its new Compound Vortex Controlled Combustion engine could exceed the standard without a catalytic converter or unleaded fuel.

本田无视传统智慧宣布，其新的复合涡流控制燃烧引擎可能超过标准没有催化转换器或无铅汽油。

Before I publish VORTEX, however, I've taken some time away from the Spin books to write an unrelated novel set in 22nd century America, to be called "Julian Comstock," based on the current Hugo-nominated novella Julian: A Christmas Story .

在《漩涡》出版之前，我会暂时离开「时间回旋」系列，拨出时间撰写一本暂时定名为《朱利安康斯多克》的小说，这本书设定在廿二世纪的美国，从入围 2007 年雨果奖最佳中篇的作品──《朱利安──一则耶诞故事》（2006，由 PS Publishing 出版）扩充改写而成。

For the head-teacher of the class said that I had seriously broken the school rules,which led me to a three-day suspend class.

为什么呢？因为我的班主任说我严重的违反了校规，于是让我停课三天。

Many of them believe that the conversion of thousands of working-class folk in England spared that nation from the mass carnage and the tyranny that came with the revolution in France.

他们之中有许多人相信，在英国数以千计的劳工阶级之悔改信主使英国免於遭受如法国大革命所造成的大屠杀和专制暴政。
