水流

According to continuity principle of flow, law of conservation of mass and Darcy's law, the dual medium mathematical model of unsteady flow in fissurekarst artesian aquifer is established, and the finite volume method is adopted to get the solution, taking Longgang district in Shenzhen as an example to verify this model.

根据水流连续性原理、质量守衡和达西定律，建立了裂隙-岩溶承压含水层非稳定流双重介质数学模型，采用有限体积法对其求解，并以深圳龙岗区为例对模型进行验证。

Enploying the coupling concept of 2D and 3D models, the initial and boundary conditions for 3D simulation of local area were provided by 2D numerical results, So the calculated results possessed excellent accuracy and rate of converg...

利用导截流数值实验室的实时数值试验，给出导截流过程关键部位的三维流速分布及水位分布，并与实测值吻合良好。这表明导截流水流特性数值实验室所采用的数值模拟技术合理可靠。

This mirror is out of the path of the light rays converging on the primary mirror and far enough off the wall of the tube to be away from tube currents, but in a position to reflect the convergent rays from the off-axis parabolic mirror.

这是出于镜面光射线道路的汇合的小镜子，远远不够的管过墙管应远离水流但能够反映收敛光线从离轴抛物面反射镜。

The results show that the coolant flow field distribution is suitable for cooling the engine.

结果表明，发动机缸头冷却水流场分布是合理的，有利于发动机的冷却。

The coil temperature and calculation of the velocity of cooling water flow are also given in the paper.

文中同时给出了线圈温度和冷却水流的计算结果。

According to different dimensions, the cretaceous groundwater basin can be divided into many groundwater flow systems.

摘要以不同的研究尺度，白垩系地下水盆地可以划分为若干地下水流系统。

The smaller cascade and crillon glaciers and the larger lituya glacier all spill into lituya bay.

有数条冰川流进此湾（较小的cascade and crillon glaciers 和较大的lituya glacier 等）立图亚湾以其落差极大的潮汐闻名于世，它西边的出海口很窄，当海水涌进便在湾内形成强劲的水流。1958年7月10日，这里发生了人类记录到的史上最高的海啸，达令人难以置信的524米高。

On the basis of research result above, the concept of critical velocity is presented and the different influences of water velocity around the critical point are study to help the future design of hot stamping mould.

在以上研究结果基础上提出速度临界值的概念，分析水流速度在临界点两侧对模具换热的不同影响，为模具冷却系统的工程设计提供了理论支持。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
