查询词典 darcy

Aiming at this problem, we have carried out an experiment on seepage properties for mudstone and argillaceous rock, showed the test result, and analyzed the reason why both the β-factor and the acceleration coefficient are negative. In addition, mistakes often made by some researchers about positive or negative signs before the non-Darcy β-factor were pointed out.

指出一些文献在引用Forchheimer关系时出现的非Darcy流β因子前正负号的错误，给出了非Darcy流β因子和加速度系数出现负值的泥岩和砂质泥岩试样全应力－应变过程中渗透特性试验结果，并对其原因进行了粗浅的分析。

If you think about Darcy, he is still a very young man trying to find himself.

The characteristic and difference of flow in porous media between the pseudo-plastic fluids and the expansile fluids was described in detail. The experimental pressure drop measurements were made in a packed bed under a variety of conditions, and the variation of the friction factor with the Reynolds number was obtained. Corresponding to the flow resistance in a nonporous channel, the flow resistance in porous media can be divided into Darcy resistance and Forchheimer resistance as well. The experiment data was divided into Darcy regime, transitional regime and Forchheimer regime in accordance with the Reynolds number.

实验测定了不同浓度聚丙烯酰胺溶液在五组填充多孔介质中流动的压降-流量关系，绘出了阻力因子随Reynolds数变化的关系曲线；按照将流动阻力分为层流粘性阻力和惯性阻力的观点，将多孔介质流动阻力分为Darcy阻力和Forchheimer流动阻力；参考有关文献，将实验区域按Reynolds数范围分为Darcy流动、过渡流动和Forchheimer流动。

For that, using Darcy law, ideal gas state equation, mass conservation law and moment equation, the paper presents the pressure distribution equation in the porous media and lubricated film including hydrostatic and aerostatic porous thrust bearings (circular pad and rectangular pad), hydrostatic and aerostatic porous journal bearings and hydrostatic and aerostatic porous spherical bearings.

为此，本文利用Darcy定律、理想气体状态方程、质量守恒定律、动量方程以及相应的边界条件，给出流体在多孔质内部和流体薄膜内部压力分布方程，结果表明这两个流动域内部流体压力分布方程是相互耦合的。

On the basis of the Darcy formula and the Cantor equation, the impact of the aperture size of concrete to its impermeability was discussed.

根据Darcy公式和Cantor方程，研究了混凝土孔径尺寸对其抗渗性的影响。

As she gradually comes to recognize the nobility of darcy's character, she realizes the error of her initial prejudice against him.

当她 8ttt8来认可darcy's字符的贵族，她体会她对他的最初的偏见错误。

A pitot tube is a pressure measurement instrument used to measure fluid flow velocity. The pitot tube was invented by the French engineer Henri Pitot in the early 1700s and was modified to its modern form in the mid 1800s by French scientist Henry Darcy. It is widely used to determine the airspeed of an aircraft and to measure air and gas velocities in industrial applications.

速度感应器，俗称空速管，最早就是法国工程师 Henri Pitot 先生发明，并在一个世纪后由另一位法国工程师 Henry Darcy 先生改进而成为现代形式的重要器件，广泛用于探测气体或液体的速度变化，并把数据传到给控制中心。

The charact eristic of groundwater flow changed appa rently under high-temperature situations.The normal Darcy′s law is not admissible at high-temperature situations.

高温差条件下，地下水体的运动规律发生明显变化，不能用传统Darcy定律来描述。

The characters in the book can be arranged in a spectrum of sensibleness, with Mr. Collins at one end and Elizabeth at the other. Somewhere in between are Darcy, Mr. Bennet, Wickham, Jane.

本书的角色在通晓事理方面可列成一个排行榜，Collins先生位居榜尾，Elizabeth则名列榜首，Darcy、Bennet先生、Wickham和Jane则介于中间。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。
