单向流动的

Generalized Darcy's law was first derived from the study of fluid flow through a solid-fluid mixture,and the saturated permeability tensor of a preform could be predicted by studying its unit cell under periodic boundary conditions.

首先，采用均匀化理论分析了流体在多孔介质内的流动问题，推导出广义达西定律，证明以施加周期性边界条件的单胞为研究对象，可以预测预成型体的渗透率张量，并以单向纤维织物为例，对该方法进行了验证。

The result is a one-way flow of air.

其结果是空气的单向流动。

The check valve avoids refluence of air in pipe- lines and consequent pressure loss in which compressed air is intended to flow in one direction only.

单向阀能防止管路中的空气回流，以及随之而来的因压缩空气朝这一方向流动而产生的压力损失。

He explained that Franklinist electrical matter cannot itself be the cause of electrical motions because it flows unidirectionally, from highest potential to lowest potential, while in the most common experiments, the same electrified body simultaneously imposes both attractions and repulsions.

他解释富兰克林的事件是因为电不能够它本身单向流动，是因为电运动的因素，从最高的位能对最低的位能，在最普通的实验方面的时候，被通电的身体一样的同时地强制吸引和击退。

Through analysis,with focus on the singularization of Macao industrial structure,the issue of unidirectional labor mobility addresses the integral and optimized policy advice.

通过分析，针对澳门产业结构单一化、就业流动单向性的问题提出整合与优化的政策建议。

A hinged valve that permits fluids to flow in only one direction and clacks when the valve closes .

瓣阀：一种铰接的阀，只容许流体单向流动，关闭时发出卡嗒声

This one-way flow of information is expensive; the last 10% of generating capacity may be required as little as 1% of the time, and brownouts and outages can be costly to consumers.

这种信息单向流动是昂贵的最后10％的发电量可能需要低至1％的时间，和灰暗的灯光，停电，可昂贵的消费者。

In this paper, the analytical solutions of reservoir pressure in Laplace space are developed for planar linear flow and radial flow under the condition of constant pressure at inner and outer boundaries, and the pressure distribution curves in some point in the reservoir are obtained using Stehfest numerical inversion algorithm of Laplace transforms.

本文在内、外边界定压的条件下得到了平面单向流和平面径向流两种渗流形式在拉氏空间的解析解，利用Ste hfest数值反演方法给出了地层各点的压力分布曲线，由这些曲线可以清楚地看到流体的流动由不稳态流向稳态流过渡以及最后达到稳态流的过程。

This paper discusses the temperature distribution in the accelerating structure of a 20MeV electron linac designed for medical use.

本文分析了一种20MeV电子直线加速器中的温度场分布，查明了目前所用具体结构与恒温冷却方式的质量水平，并与国外某些加速器所用的单向流动冷却方式在优缺点方面作了对比。

Special emphasis should be put on the parallel connection of Venturi mixer, for it can avoid the stalling disadvantage of series-wound connection of Venturi mixer, enlarge the modulating range of EGR rate enormously, and make the best of Venturi mixer.

在前文建立的性能与排放综合预测模型基础上，增加简化的EGR管路流动模型，首次将排放预测与实时EGR管路流动结合起来，进行单向阀EGR系统的性能与排放综合预测。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
