气泡形成

A long wake with lots of bubbles is formed behind a sailing ship, which provides a target feature of the ship.

舰船航行时在尾部形成一条含有大量气泡的尾流，成为舰船的目标特征之一。

Foams are cushiony material formed by the creation of gas bubbles in a base material such as natural rubber, synthetic rubber or other elastomeric materials.

它们是由气泡在一种基本材料如天然橡胶、合成橡胶或其它弹性材料中的产生而形成的软垫材料。

Cation group has the capability of charge neutrality and this would make oily wastewater demulsify and remove oil easily. Hydrophobic group would improve hydrophobic-oleophilic nature of the oil granule. Simultaneously, wetting reversed agent would change wetting performance of oil granule, enhance conglutination capability between air bubble and oil granule. And Frother would form bigger foam layer on the water, so it could prevnt granule with air bubble from rolling downward.Using the hydrophobic polymeric flocculant as one of ingredients for flotation agent formula, the flotation agent has good treatment effect.

浮选剂配方中的疏水性高分子絮凝剂分子链上带有的阳离子基团起到电中和作用，使含油污水易于破乳除油，而疏水基团能增强颗粒的疏水性能；润湿反转剂能改变颗粒的润湿性，增强气泡与颗粒的粘附能力；起泡剂在水面能形成强度较大的泡沫层，起阻止带气絮粒向下翻动的作用。

A part of the volume of siol air is easily surrounded by water flow and entrapped in the pores of soil in the infiltration progress.

非饱和土体中的部分气体极容易在入渗过程中被封闭在孔隙或裂隙中，形成互不连通的与外界隔绝的封闭气泡。

Made in massive 200 pound wheels from pure, unpasteurized cow's milk, this special "Swiss" is aged for at least twelve months in sandstone caves deep below the Santenberg in the Canton of Lucerne.

切开这种奶酪，可以看到在淡黄色的奶酪上，布满了大大小小的气孔，那些孔是在奶酪的发酵过程中由碳酸形成的气泡，通过这些孔的样子就可以知道奶酪的发酵是好是坏。

You will without doubt have small and medium bubbles on the surface of the milk at this stage.

在这一阶段，毫无疑问你在牛奶的表面已经形成小的和中等大小的气泡了。

A low superheat wall temperature area occurs during the nucleating, and it is larger than the bubble radius.

空穴成核过程中形成的低过热区域超出了气泡直径大小，影响因数在1.3-1.8范围内变化。

A blowing agent, such as the polyester polyol used in this experiment, forms gas bubbles in the reaction as it polymerizes.

一个吹的代理，譬如聚酯多羟基化合物被使用在这个实验，形成气泡在反应当它聚合。

So less gas is given off in the mould than with rimming steel, but enough bubbles form at the top of the ingot to counteract most of the shrinkage

所以，在钢锭模内析出的气体没有沸腾钢多，但又在钢锭头产形成足够的气泡抵消大部分钢的收缩。

In the high efficiency oil removal technology aspect, the theory study and application experiment of air sparged liquid-liquid hydrocyclone was carried out, enlightened by the air sparged solid-liquid hydrocyclone. Firstly, the strength and movement of dispersed phase was analyzed in theory, it was proved that the air bubble-oil drop polymer trend to move to the axes of hydrocyclone. Secondly, using CFD method, the characteristics of oil-air-water flow field were studied, including velocity distribution, pressure distribution, turbulent motion energy and its dissipation distribution. The characteristics and separation effect under different air injection methods were simulated. Thirdly, the separation ex-periment of air sparged liquid-liquid hydrocyclone was carried out at Lab. The major structure parameters of the hydrocyclone were optimized, the reasonable air injection method and performance parameters were determined through 4 groups of air injection experiments.

首先，对气携旋流场中分散相粒子的受力及运动进行了理论分析，证明了气泡与油滴形成的聚合体，更易于向轴心运动；其次，应用CFD方法，研究了油-气-水三相流场的速度分布、压力分布、湍动能及其耗散率分布特性，对不同注气方式的流场特性及分离效果进行了数值模拟；第三，开展了气携液-液旋流分离特性室内研究，优化了旋流器的主要结构参数，对四种注气方式的分离效率进行了对比，确定了合理的注气方式和操作参数；最后，在油田现场开展了处理聚驱采出污水工艺试验，确定了工艺运行参数，评价了处理效果。

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。
