查询词典 vortex plate

In 1906, da Rios, a student of Leivi-Civita, wrote a masters thesis modeling the motion of a vortex in a viscous fluid by the motion of a curve propagating in R~3, in the direction of its binormal with a speed equal to its curvature.

很久以后，1971年Hasimoto证明了这个系统和非线性Schrodinger方程 q_t=iq_(ss 1/2|q|~2q是等价的。

The results show that as the wind is along one leg of the model, the vibrations which are mainly caused by turbulence of oncoming flow are weak, and as the wind is along the angular bisector of two legs, the vibrations induced by vortex are strong.

实验结果表明：当风向顺Y型柱体某一肢时主要是来流脉动引起柱体较弱横向振动；当风向顺Y型柱体两肢分角线时则由涡脱落而引起柱体强烈的横向振动。

As to the response of vortex glass and Bose glass to externalforce, we found the results are different .

并且发现磁通玻璃和玻色玻璃对外力的响应是不一样的。

Both sides of intake maybe occur intermittent inspiration vortex with high flow flood in floodplain. It can be subtracted by means of inclining the breast wall to the upstream.

大流量漫滩洪水时进口两侧可能出现的间歇性吸气漩涡，可采用将胸墙向上游倾斜的方式予以消减。

From this landing, you look down on a twisted vortex of line and space that van Berkel describes us a kaleidoscopic dynamism, where mobility and materiality come together' If there were a remake of the 1971 film Diamonds are Forever, this stair and living room should be the place where the Amazonian bodyguards cavort with James Bond, rather than John Lautner's Elrod House (1968 ), which was the setting in the original film.

从这个着陆，你看不起的线路和空间扭曲的漩涡，面包车伯克尔描述了我们一个万花筒般的活力，流动性和重要性的地方走到一起'如果有一个1971年的电影重拍钻石是永恒的，这个楼梯和客厅应该是地方亚马逊保镖与007，而不是约翰劳特纳的埃尔罗德楼（1968年），这是在原来的电影设置跳跃。

The central angle of the impingement fluid separated from the target surface became larger with the increase of jet Reynolds. And the separating angle also increased with the increasing ratio of the jet distance to the diameter of the jet hole, while the range of induced vortex became smaller.

试验中发现随着冲击雷诺数的增加，冲击气流与壁面分离处对应的圆心角增大，分离推迟；随着相对冲击间距值的增加，气流与壁面分离处对应的圆心角越来越大，相对于受限空间的大小，诱导涡的范围越来越小。

Above: In Charybdis the circular movement of water inside a transparent acrylic cylinder forms an air-core vortex in the centre.

上图：在卡律布狄斯中，水于透明丙烯酸圆桶中的环状运动轨迹，在圆中形成了空心涡流。

An improved model of curved vortex element on the circular arc for rotor free wake analysis is presented.

涡元技术是尾迹分析的基础，本文第二章改进了先前的曲涡元模型。

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。

After explaining total design of automated test system for microcircuit , the thesis introduces GPIB standard .

文章在说明了微电路模块自动测试系统的总体设计后，对GPIB标准进行了介绍。

He interceded in my behalf.

他替我说情。
