不流动的

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。

Rather than loading ships, they spend their days in front of computer screens, moving zillions of dollars, pounds, euros and yen around the globe at the flick of a key.

不同于以往的港口城市，如今的他们日以继夜地坐在电脑的屏幕前，通过简单地敲击着键盘，谈笑之间，数额庞大的美元，英镑，欧元和日元就在他们的指间在全球流动。

Emerging economies are being hit hard by weakening exports and the collapse of private capital flows. The G20 summiteers cannot prevent this, but they can stave off a slump with zealous and co-ordinated action to prop up domestic demand and provide resources to cash-strapped emerging economies.

新兴经济体因为出口下滑和私有资本流动崩溃而备受挫折。G20峰会的领导人不能阻止这一切的发生，但是通过统一协调并且目标坚定的行动来提升内需和为缺乏现金的新兴经济体提供资源，他们还是可以缓解下挫的幅度。

The drama and effort of the barn-building in "Witness", underlined with the mounting rhythms of a passacaglia; the first stirrings of sexual feeling in "A Passage to India", pointed by sitars; and Lawrence bowing ecstatically to his own flowing shadow in the desert, a moment now never recalled without Mr Jarre's soundtrack welling behind him.

目击者》中建造农仓时，渐强节奏的帕萨卡里亚舞曲所突出的戏剧效果；《印度之行》中锡塔尔琴所点醒的性感骚动；以及看着自己影子在沙漠上流动而狂喜的劳伦斯，那一时刻，若没有贾尔先生的音乐在他身后涌流，就不会在人们脑海里再现。

However, more and more studiespresent that the local pressure fluctuations in the separated and reattached region of bluff body are found tobe non-Gaussian. The Gaussian assumption will underestimate the wind load of cladding and cause thecladding to unsafety. It is a general way to estimate peak pressure by a fixed peak factor.

然而，有越来越多的研究表明，钝体绕流的分离和流动再附着区域的风压呈现出强烈的非高斯分布的特性，按照高斯分布进行峰值风压的估计将可能低估作用于围护结构上的风荷载而造成结构的不安全性。

The inflow rate along the wellbore is not equivalent, but distributes like"U"shape, and inflow rate of the two ends is higher than that of the middle part. When the inflow reaches its pseudo steady flowing, the distribution shape of flowing keeps steady.

5井筒压降80％出现在距水平井跟端50％的井长内，沿水平井简单位长度的流入量并不相等，沿井筒形成U形流入分布，在水平井的两端的流入比井筒中部的流入相对要高，一旦达到拟稳态流动，沿井筒的流入分布形状基本保持不变。

It is found that the position of vortex shedding is different fro m three-row cylinders. The time-mean pressure coefficient along the surfaces o f the cylinders is not changed with the void friction. But the fluctuating press ure coefficient reduces with the increase of void fraction.

试验结果表明：沿圆柱表面周向的旋涡分离点随着流动向深层发展，并向圆柱的背部移动；圆柱表面沿周向的时均压力系数几乎不随含气率的变化而变化；圆柱表面的脉动压力系数随着含气率的增加而减小。

Phase-lagged cyclic boundary condition is implemented by a novel method in conjunction with the developed sliding interface technique to accurately simulate the arbitrary pitch ratio rotor/stator interaction without any modifications of the physics of the problem. It's for the first time to compose the computational area into one structured grids including both rotor/stator of centrifugal or axial turbomachinery with arbitrary pitch ratio. This method can eliminate the iteration of boundary conditions on the sliding interface and calculate the unsteady flow within rotor and stator simultaneously.

为了能够在较小的计算区域内不改变叶型而真实地反映出任意栅距比时的内部非定常流场，并避免近似仍采用相位后滞周期性条件，结合本文发展的网格技术，给出了一种新的实施方法，首次将动、静叶片数不等的离心式/轴流式叶轮机械转子、静子计算区域组合在一套结构化计算网格中，动/静叶排间的滑移界面完全按内场处理，避免了每一时层内，滑移界面处边界条件的迭代计算；并保证了每一时层，滑移界面处流动参数的守恒特性。

The results show that the temperature of the alloy gradually decreases from the casting mouth to the exit in the roll-shoe gap, and the isothermal line deviates from the shoe side to the roll side.

结果表明：辊靴型腔内合金的温度从入口至出口逐渐降低，合金等温线向工作辊偏移；随着浇注温度的降低，辊靴型腔内半固态区间逐渐增大；为了获得优良的半固态金属浆料，确定浇注温度为710~770 ℃；合金在辊靴型腔内层流运动时，越靠近工作辊内表面，合金的运动速度越快；随着挤压模具扩展角的增大，挤压模具出口型材宽度上中心与两侧边部合金的温度差减小；半固态合金进入模具后呈辐射状逐层向前推进填充模具扩展腔，最后再逐渐向模具出口合拢；为了改善模腔内金属流动速度的不均匀性，扩展角以45为宜。

An excellent, accurate and reliable movement when serviced by competent watchmakers, but not known for its ability to withstand abuse Then of course we have a few Seiko and Citizen movements that have an outstanding reputation for their toughness and reliability, but most of them fall short in the accuracy department, and one is fortunate if they are accurate to better than +- 15s per day.

良好的，准确和可靠的流动提供服务时，由主管钟表，但不知道是因为它有能力承受滥用那麼当然我们有几个精工与公民运动，有一个杰出的声誉，他们的韧性和可靠性，但其中大部分属於短期在新闻部的准确性，一个幸运的是，如果他们是准确优於+- 15每天。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
