查询词典 darcy

It is often tested by an unsteady state flow experiment and calculated by JBN method,which is only fit for Darcy flow through medium-high permeability with high velocity of displacement because of taking neither non-Darcy flow nor capillary attraction into account.

通常用非稳态流方法测定和用JBN方法计算它，但未考虑非达西流及毛管力的影响，故只适合于中高渗透岩石达西渗流的情形，且要求非稳态相对渗透率实验驱替速度较高。

The influences of Darcy number and inertia parameter on the velocity profile of the structural flow are analyzed,and it is shown that the velocity profile becomes evener with Darcy number decreasing and the inertia parameter increasing.

随着所施加的外力逐渐增大，管壁附近的各流层依次开始流动，而管路中心的流体仍然以相同的速度，像圆柱体一样向前运动，这部分流体称为流核，流核内部的流层间没有相对运动，具有流核的流体流动称为结构流

The result is, at times, kind of like Enigma without the smarmy, moustache-twirling sexuality; the parallel is especially noticeable when vocalist Darcy starts whispering in her rather poorly pronounced French ("Breathe,""I Am").

因此，我们不时会听到类似于Enigma的元素，然而却没有后者的刻意迎合，以及moustache-twirling的香艳；当Darcy用她那颇为蹩脚的法语低吟浅唱时，我们更是看到了专辑足以与Enigma匹敌的实力。

Using the coordinate transform method, the strain tensor transformation relation and the objectivity hypothesis, the rational forms of Darcy' law in both spatial description method and material description method are derived respectively, as well as the seepage coefficient expression for large-strain deformation coupling.

采用坐标和应变张量变换方法以及客观性假设，分别导出Darcy定律在空间和物质描述两种情况下的合理形式，同时还推导变形耦合情况下大变形法渗透系数的表达式。

Darcy\'s law was first successfully applied in analyzing water conductivity characteristics of xylem on above basis.

在此基础上，首次成功地将Darcy定律应用于树木木质部的导水特征分析。

Darcy Paquet, a film-buff and lecturer who runs a Korean film fanzine, says: the tragic story seems made for the screen, very little was altered in its telling.

Darcy Paquet，学者，电影迷，还是一家电影爱好者杂志的老板，他说：这个悲剧故事似乎是为电影度身定做的，拍成电影时改动很少。

Displacements, strains, the net stresses for the solid phase; pressures, pressure gradients, Darcy velocities for pore water and pore air phases; temperature, temperature gradients, the heat flux of the three phase mixture are interpolated as independent variables.

固相位移、应变和净应力；孔隙水和气的压力、压力空间梯度和Darcy速度；多相混合介质的温度、温度空间梯度和热流量在单元内均为独立变量分别插值。

In the paper, we investigate, respectively, the unsteady transport properties of heat and moisture in enclosure under constant wall heat flux and constant wall temperature when porous particles are small and Darcy number is lower, the effect of conductivity ratio, heating conditions and other parameters on the heat transfer rate of enclosure when particles are larger and Darcy number are higher.

并分别对多孔颗粒较小时的低Da数封闭腔内的非饱和渗流与传热，及颗粒较大的高Da数封闭腔内的非饱和自然对流行为进行了数值模拟，研究了低Da数时湿分与热量在恒热流与恒壁温条件下的非稳态传递特性，高Da数时封闭腔的传热与流动特性、达西效应以及导热比、加热条件等对空腔传热系数的影响。

Corresponding to the Darcy-Richards equation, hydraulic resistance and resistivity are the reciprocals of conductance and conductivity respectively; time constant is the reciprocal of the diffusivity; and time constant per unit squared length is the reciprocal of diffusivity.

与Darcy-Richards方程相对应，水阻、时间常数分别为导水度、水分扩散度的倒数，相应地单位化的水阻率、比时间常数分别为导水率、水分扩散率的倒数。

The theories proposed by Wilson (1994) were adopted to describe the fundamental behaviors of temperature and variation of suction of soil. The Darcy's law and Pick's law described the flows and evaporation of water respectively. Some proposed assumptions including the characteristic curve of volumetric water content and hydraulic conductivity were only related to the suction of unsaturated soil. The coefficient of latent heat for water was a linear function of temperature; and the heat conductivity was calculated according to the equation proposed by De Vries.

对于土体的温度和吸力变化特征，采用Wilson提出的理论加以描述，在此理论中，分别利用Darcy和Fick定律描述水和蒸汽的流动规律，土水特征曲线和水力传导系数假定仅仅相关于非饱和土吸力，水的潜热系数是温度的线性函数，温度传导系数采用De Vries建议方程加以计算。

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。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
