水力学

Hydromechanical coupling of jointed rock mass was the key point for problems of hydraulics of rock mass.

裂隙岩体的渗流应力耦合机理是岩体水力学的研究重点。

The hydraulic properties of rock masses are likely to be highly heterogeneous even within a single lithological unit if the rock is fractured.

由于岩体中通常包含有大量的各种尺度的裂隙，因此其力学和水力学性质即使是在单一岩性岩层中也是高度非均质的。

All of these indicate that the combination of geography information system and hydrology and hydraulic model is an effective way of nonstructural flood control measure.

以此证明了地理信息系统与水文水力学模型相结合是实现非工程防洪措施的有效手段。

Finally, hydraulic variables were simulated and analyzed in the progenitive field of the Chinese Sturgeon below the Gezhouba Reservoir.

模拟结果表明三峡水库建坝后各水力学要素都有不同程度的减小，这可能会对中华鲟的繁殖产生一定的影响。

Based on the hydraulics theory a research has been made on change of hydraulic head and discharge through orifice in filter underdrain system,and some mistakes have been illustrated in reference.

运用水力学原理，对滤池配水系统中水头和孔口出流量的变化进行了研究，并指出文献［1］、［2］、［3］对该问题的错误所在

According to the aquatic ecosystem investigations in October of 2003 and April of 2004, the composition and quantity of phytoplanktons after impounding of the Three Gorges Reservoir were studied. We discussed the influence of water dynamics condition, water nutrient level on the phytoplankton components and quantity.

根据2003年10月和2004年4月的水生生物调查，对三峡库区二期蓄水后的浮游植物组成与分布变化进行研究，探讨水力学与营养盐条件变化对库区浮游植物结构与数量的影响。

Optimum position of a bottom tuyere and amount of gas blowing in a combined blowing converter were determined by measurement on perfect mixing time of metal bath via water model experiments.

采用水力学模型试验，通过测定熔池均匀混合时间长短，确定复吹转炉底部供气元件最佳位置和供气量。结果是单支底部供气元件偏心布置在炉底耳轴方向0.4D位置，供气量在0.557～0.928m3／h的复吹熔池均匀混合时间最
