流体的

Examples are industrial discharge such as brine, living sewage disposal, cooling water of power plant which is discharged to the river, dust or waste hot gas which is let to the atmosphere from chimney and cooling tower, and bilge water which is released to the port water area.

当废水或废气排放到环境流体中时，废流体的密度往往与环境流体的密度不同，这种由于密度差而产生的浮力不仅影响平均流本身，而且更主要的影响湍流及受湍流影响的动量、热量和质量的交换。

In order to study the stability of non-Newtonian fluid and its flow pattern discrimination method,the integral stability theory and local stability theory are applied to the concentric annulus flowing of plastic fluid and power-law fluid,then a relevant stability parameter expression of discriminating flow pattern is derived and set up in the paper.

针对非牛顿流体的稳定性问题及其流态判别的研究，将整体稳定性理论及局部稳定性理论应用于塑性流体和幂律流体在同心环空的流动中，建立和推导出相对应的判别流动状态的稳定性参数表达式。这些参数的临界值与牛顿液体流态准数雷诺数的临界值，同样具有与液体流变性无关的特点。

At the latter consolidation stage, it was assumed that the water flow only depended on water pressure and was not influenced by the air. Then the independent continuity equation of water was set up to solve variation of water pressure with time. Besides, the water and air were regarded as mixed fluid, and the continuity equation of mixed fluid was set up.

在其后的固结过程中，假定水的流出仅仅取决于水压力，不受气的影响，单独建立水的连续性方程，解水压力随时间的变化；又将水和气看成混合的可压缩流体，建立混合流体的连续性，解混合流体压力随时间的变化。

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。

In this paper, we describe the characteristics of near critical hydrocarbon system and summarize the development and application of empirical and unempirical EOS in near critical fluid about PVT phase analog.

Two different velocity potential functions corresponding respectively to the liquid above and below the damping spacer are assumed.

研究表明：在相同密度分布条件下，可压缩流体的界面扰动增长速率总是比相应的不可压缩流体的界面增长率大，其相对增长率D随扰动波长的增加而增大，也随两种介质的声速减少而增大，在长波和易压缩流体中，D值可达0.8以上。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
