速度分布

In this dissertation, the numerical method and optical interferometry experiment for isothermal EHL of finite line contacts are studied. The effects of the profiles and the rolling velocity on the film shape, film thickness as well as pressure distribution of the film are discussed.

本文以滚子类轴承为研究对象，对等温有限长线接触弹性流体动力润滑理论的数值分析方法和光干涉试验进行了研究，探讨了等温油润滑条件下，光滑表面滚子的凸型、凸度量等几何参数和滚动速度与弹流油膜形状、油膜厚度和油膜压力分布之间的关系。

To cope with this problem, we used gamma inversion to rule out the low velocity anomalies that caused by incr...

针对这种情况，采用伽马反演，来排除因泥质含量增加形成的低速异常现象，再结合速度反演，较准确地预测出了双家坝地区飞仙关组鲕滩的发育情况，落实了其分布范围，为下一步勘探提供了可靠的资料。

By comparing several turbulent models, standard k -εmodel , renormalisation -group k -εmodel, realizable k -εmodel, standard k -ωmodel, shear stress transport k -ωmodel, it can be concluded that the RNG k -εmodel predicts more realistic results than the other models used in the simulations.

比较分析Standard k -ε模型、RNG k -ε模型、Realisable k -ε模型、Standard k -ω模型及SST k -ω模型模拟缩放型喷嘴产生空化水射流流场，结果表明RNG k -ε模型更适合数值模拟缩放型喷嘴内的射流压力速度等分布状态。

The velocity, pressure and streamline distribution of the internal flow field of front guide impeller are analysed.

分析了前置导轮内部流场的压力、速度和流线分布情况。

There is a clear correlation between seismic activity and Pn velocity variation. Most earthquakes are concentrated in the northcentral Tien Shan with high Pn velocities, while almost no earthquakes located in the southcentral Tien Shan with very low Pn velocities.

Pn波速度的变化与地震分布有着密切的对应关系：地震大都发生在中天山北部Pn波高速区上方，而南部的Pn波低速区上方几乎没有地震。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
