82 Times as high as the flow rate at the inlet; the velocity profile in the lower region is relatively uniform, and changes at the exit from a parabolic shape towards a plug flow as Re increases; The strong circulating flow in the upper region is very favourable to evaporization of heated fluid because it not only forces all the heated fluid to flow through the liquid surface and, therefore, to evaporate effectively, but also causes a large part of fluid to recirculate to the liquid surface and, therefore, to get a second opportunity of evaporization. In addition, the uniform velocity profile in the lower region is also favourable to crystallizing process.

轴向进料蒸发室进口管侧上方有强烈的循环流存在，循环流流量为进口流量的1.48～1.82倍；循环流下部流速分布较均匀，出口区流速在低Re时为抛物线分布，高Re时接近活塞流；强烈循环流的存在不仅迫使加热流体全部流经液面及其附近进行充分蒸发，而且之后还使相当部分流体再次循环回到液面及附近进行二次蒸发，对蒸发操作十分有利；蒸发室下部流速的均匀分布亦有利于蒸发结晶过程。

From the fields of regional crust-mantle structure, metallogentic settings, history of tectonic-magmatic activity, distribution of high antimony anomaly, characteristics of deposit, origin of ore-forming materials (including Sb, C, Si, S, solution and associated elements), black dikes, the relation of deposit and mantle metasomatism fluid is expounded by means of geology and geophysics. Xikuangshan antimony deposit is proved to be a typical vein deposit formed by mantle metasomatism fluid. On the basis of this knowledge, the prospecting criteria of blind orebody of the deposit are given as follows: extensive structuer which indicating the activities of mantle metasomatism fluid, change of host rocks (especially exsisting shale barrier bed), silication and carbonization alteration.

文中对地幔交代流体组成、性质、活动特点及其成岩、成矿作用作了综述与探讨；从锡矿山区域壳幔结构和成矿背景、地质构造-岩浆活动史、高锑地球化学场结构分析、矿床特征、成矿物质(包括Sb、C、Si、S、流体及伴生元素)、与成矿有时空联系的暗色脉岩等方面入手，利用地质、地球物理、地球化学手段多方面论述了矿床与地幔交代流体活动的关系，论证了锡矿山超大型锑矿的地幔交代流体成因，并以此为基础提出盲矿体地质找矿标志：即指示地幔交代流体活动的构造，尤其是具有成矿元素和碱质异常、热液蚀变的断裂构造；有利的岩石物理化学性质；硅化、碳酸盐化围岩蚀变等。

Pleural effusion is broken down into two categories, transudates and exudates. A transudate is a clear fluid that forms not because the pleural surfaces are diseased, but because of an imbalance between the normal production and removal of the fluid. The most common cause of transudative fluid is congestive heart failure.

型胸膜流出为二类别、transudates 和渗出液被划分。transudate 是形成的纯净流体不是因为胸膜表面是害病的，但由于一种不平衡状态在流体的正常生产和撤除之间。transudative 流体的同道会是充血的心力衰竭。

Considering the influence of fluid's viscosity and large amplitude sloshing, the 2-dimension coupling system composed of uncompressible viscous fluid and ideal elastic structure of rectangle aqueduct is studied by using ADINA to develop the models in this paper. Analyze the dynamic response of the rectangle aqueduct structure by large amplitude liquid sloshing. Under the horizontal harmonic excitations with different amplitudes, analyze the harmonic response of the rectangle aqueduct structure and fluid, include pressure on the tank wall ,free surface height and so on.

本文应用大型通用有限元软件ADINA探讨了计入流体的粘性、大幅晃动影响，不可压缩粘性流体与矩形渡槽弹性体的二维动力耦合问题，分析流体的大幅晃动对矩形渡槽结构所带来的动力影响问题；在水平谐波激励方式下，针对不同的激励振幅和激励频率，研究渡槽结构和水体的振动反应包括渡槽结构的倾覆力和倾覆力矩，水体自由液面角点的波高和水体底部角点的动水压力的反应分析。

Second, try using structure: as in Woolf, where the 6 chapters do allow you to locate some "shape" undergirding her stream, the acts (and, dare I say it, all those scenes) also help structure one's thinking about this most fluid of Shakespeare's plays: Fluid in imagery, in diction, in location, and fluid in our perspectives on the characters.

其次，试着组织架构：如在吴尔芙的六个章节中，的确能让你找出某种支持她的思路的&模型&；各幕也能协助你整理思路以了解莎士比亚剧作的流畅性：流动的形象、用字、地点以及我们对角色的理解。

Mechanical type variator and the fluid drive automatic transmission compare, may compare favorably with in the operation conveniences and the riding comfortable aspect with the fluid strength bending moment, but its transmission efficiency far is higher than the fluid moment of force actually.

机械式无级变速器与液力传动自动变速器相比，在操纵方便性和乘坐舒适性方面可与液力变矩器相媲美，而其传动效率却远高于液力矩器。

BACKGROUND: Conventional concept suggests that infused crystalloid fluid is first distributed in the plasma volume and then, since the capillary permeability for fluid is very high, almost instantly equilibrates with the extracellular fluid space.

背景：一般我们认为输入晶体液在血容量中是一室分布的但因为的毛细血管通透对晶体液是很高的，所以晶体液在血管内与细胞外间隙立刻就会达到平衡。

In the days of sailing vessels the crew were afraid they would be becalmed on the ocean.
