界面

Interfacial surface tension is the resistance to separation possessed by a film of liquid between two well-adapted surfaces. It is the result of the cohesive forces acting at the surface of the liquid.

界面表面张力是指两个具有良好密合性被液体薄膜粘附的界面抵抗被分离的能力。

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。

For the prediction of vapor liquid interfacial tension of fluid mixtures,hard sphere surface tension model of pure liquid proposed by Reiss has been extended to mixtures using two vdW 1 mixing rules.The surface tensions for 64 binary liquids have been correlated with only average relative deviations of 0.80%.With the parameters obtained from the correlation of binary system data,this method has been satisfactorily applied t...

应用定标粒子理论表面张力方程以及 vd W- 1型混合规则，计算了混合流体的表面张力，对 64个二元体系，7个三元体系的表面张力计算平均相对偏差为 0 。80 %和 2 。43%；应用 Boudh- Hir和 Mansoori提出的部分互溶体系的界面张力模型，给出了硬球直径的确定方法，对 37个部分互溶二元含水体系的界面张力进行了计算，绝对平均偏差为 1 。5m N/m，相对平均偏差为 8.9%，计算精度满意。

However, due to the complicated transfer mechanisms at the interface coupled with the motion and geometry of the interfaces, it is difficult to model the interfacial transfer terms in two-fluid model.

然而，由于两相交界面的复杂性、多变性、随机性，两流体模型中有关相界面传输项的模化仍是多相流研究领域的一个难题。

According to the results of this study, the ultimate strength of pin-bone interface increased as the moment arm decreased and torque increased. When the pin-bone angle approached 90°, the ultimate strength was the largest and as the angle decreased, the ultimate strength decreased. There was no significant difference between rigidity and torque, but rigidity decreased as the skull-bone angle decreased.

结果发现钉骨界面的极限强度在头圈距离颅骨的力臂短时较高，且随著所用扭力的增加而增加，当头钉与头骨表面的夹角成垂直时最强，随著夹角越趋锐角而渐减，钉骨界面的刚性与扭力并无明显关系但与夹角有关，夹角垂直时刚性最高，而后随著夹角渐趋锐角而递减。

Some oil fields have a mat of heavy tar at the oil water contact. This mat is produced by the degradation of oil as bottom waters move beneath the oil-water contact.Tar mats cause considerable production problems by inhibiting water from displacing oil.

由于油水界面下面底水的流动造成了原油的降减作用，一些油田的油水界面处常形成一种重油垫，由于重油垫阻止了水对油的替换作用，因而造成了许多严重的生产问题。
