Effects of Coriolis force were analyzed with the three dimensional simulations and the following conclusions were drawn: The tangential component of Coriolis force induces cross stream secondary flow in the form of two-cell pattern,while the radial component of Coriolis force decelerates and accelerates the cent...

计算结果表明，切向哥氏力推动了通道截面内的双涡二次流，径向哥氏力则使得近侧壁流体加速和中心流体减速。换热计算结果从定性趋势上吻合公开文献中的实验现象，反映了旋转附加力的基本影响规律。

With the deeping of the trough and the westward moving of the tropical cyclone, the low level vortex and wind shear line extended along a southwest - northeast orientation over the Yangtze River. On the effect of high, middle and low latitude systems, a rainband in southwest - northeast orientation formed gradually.

随着阻塞形势的发展和热带气旋的西移北上，经向环流加强，主要影响天气系统——低空的低涡切变线沿西南－东北方向伸展，在高、中、低纬度天气系统的共同作用下，一条西南－东北走向的雨带逐渐形成。

Following the latter idea, a general form of scalar eddy viscosity models is derived in this paper by introducing two hypotheses. Meanwhile, the realizability of this kind of models is discussed too.

本文遵循后一种思想，在引入两个假设后，推导出标量涡粘性模型雷诺应力的一般表达式，并讨论了其可实现性条件。

Reynolds number of impingement, inclined jet angle, the ratio of the jet distance to the diameter of the jet hole and the relative curvature (the ratio of the diameter of jet hole to the diameter of concave surface) were changed to study the rules of flow structures varying with these parameters. At the same time, the developing and disappearing phenomena of the induced vortex were analyzed.

通过改变冲击雷诺数、冲击角度、相对冲击间距（冲击间距和冲击孔直径之比）以及相对曲率（冲击孔直径同凹面靶板直径之比）等参数，分析了受限空间中，斜向冲击曲率表面后产生的涡系结构及其发展和变化规律。

In order to investigate the influence of surface tension gradient driven convection on solidification behavior of alloys under microgravity, remelt and solidification of Al-Al〓Ni eutectic alloys, which have characteristics of directional growth along temperature gradient, were carried out on board Chinese retrievable satellite.

利用我国返回式科学实验卫星搭载的梯度炉和Al-Al〓Ni共晶合金定向生长的特点，研究了与重力无关的表面张力驱动对流（Marangoni对流）对合金凝固行为的影响，在空间微重力下获得了弯曲的双涡放射状共晶组织。

When applied to a certain type of turbo engine, the result showed that the proposed model has high resolution for locations of pressure signal singularities, which are caused by stall air mass in the compressor; this method can be used in the early detection of surge signal.

对某型涡喷发动机压力测量信号的分析结果表明，该方法对由失速气团造成的压力信号突变具有较强的分辨力，可以用于发动机喘振的早期检测。

The results showed that compared with smooth surface, there was secondary vortex in micro flow field;, the viscous sub-layer in the near region of riblet surface was thicker; turbulence intensity was depressed and riblet surface was hydrophobic.

研究表明，与光滑表面相比，脊状表面微观流场结构中存在2次涡，近壁区的黏性底层厚度比平板的要厚得多，湍流度显著降低，且脊状表面表现出明显的疏水性。
