查询词典 vortex

The invention concerns a burner comprising a premix designed to produce a flammable air-fuel mixture, said burner including a vortex generator, wherein are provided two complementary burner shells forming a passage body, having each a first half-cone burner shell section (1) and delimiting together a turbulence chamber, widening in the axis in the form of a cone, as well as tangential air intake slots in the axial longitudinal direction of the cone.

描述了一种用于产生可点燃的燃料-空气混合物的预混燃烧器，该预混燃烧器具有涡流发生器，该涡流发生器设置了至少两个对穿流本体进行补充的燃烧器壳，所述燃烧器壳分别具有构造为分锥形状的第一燃烧器壳区段(1)并且共同限定着在轴向上按锥形方式扩展的涡流室并且限制着所述沿轴向的锥体纵向伸展方向相互相切的进气缝隙。

The use of baffle can restrain the vortex and can result in a strong axial flow.

加入挡板能限制旋涡的产生，并在轴向上产生强烈的流动。

Boundary layer on the shroud is pumped after bleeding, which restrained the disturbance induced by the interaction of low energy airflow and mainstream, delaying the adverse effect of Clearance flow backwards and improving the mainstream of compressor, weakening the characteristic of leakage vortex, bating the blockage of blade passage at a certain extent.

采用引气后，抽吸机匣壁面上的附面层，抑制了低能量气流与压气机主流的干扰，减缓间隙倒流的负面影响，在一定程度上削弱了泄漏涡的特性，减弱了叶片通道的堵塞状况，改善压气机主流流动。

In one side, the asymmetry of flow beget vortex and the separation of airflow which is the cause of pressure losses.

首先流动的不均匀性，一方面产生涡流和气流分离现象，引起流动阻力的增加；另一方面，造成温度分布的不均匀。

As a whirlpool of boiling waters has a centre point, so, all this raging circled round Defarges wine-shop, and every human drop in the caldron had a tendency to be sucked towards the vortex where Defarge himself, already begrimed with gunpowder and

"呃，这儿，你看见的！"老板娘仍然跟任何时候一样镇定，只是没有织毛线。她那坚定的右手攥住的是一把斧头，而不是较为温和的常见工具，腰带上还插了一把手枪和一柄残忍的刀。

As a whirlpool of boiling waters has a centre point, so, all this raging circled round Defarge's wine-shop, and every human drop in the caldron had a tendency to be sucked towards the vortex where Defarge himself, already begrimed with gunpowder and

"呃，这儿，你看见的！"老板娘仍然跟任何时候一样镇定，只是没有织毛线。她那坚定的右手攥住的是一把斧头，而不是较为温和的常见工具，腰带上还插了一把手枪和一柄残忍的刀。

Ensemble GRENZENLOS is to bring us a number of music works which premiere in China, including Vortex Temporum by Gérard Grisey, one of the founders of French Spectral Music, Air from Opera by Luciano Berio, a well-known Italian composer, Tetras by Iannis Xenakis, a famous Greek composer of stochastic music, 'Grido' String Quartet by Helmut Lachenmann, a German composer of noise music.

多国组成的无疆界新音乐团为我们带来了许多中国首演的作品，比如法国频谱学派鼻祖格里塞的《旋涡》、意大利著名作曲家贝里奥的《咏叹调》、希腊著名随机作曲家泽纳基斯的《忒塔》和德国噪音作曲家拉亨曼的弦乐四重奏《哭泣》。

By means of linear trend estimate, Morlet wavelet analysis and binomial coefficient smooth, the interdecadal variation characteristics of north polar vortex and spring precipitation in China are studied.

各季节极涡面积及强度均存在显著的年代际变化，在20世纪70年代中期之前有上升趋势，而后出现下降的趋势；但极涡面积总体上有显著的线性变小趋势。

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。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
