气泡

Childhood, I often like to blow bubbles, looking at the colorful bubbles under the sun, my heart is full of treatments, with age, I feel that life is filled with countless colorful bubbles, each bubble is Each bubble contains a story with joys and sorrows of life, and I and everyone else, enjoying the life of the bubbles.

儿时，我常常喜欢吹泡泡，望着阳光下五颜六色的气泡，我的心中充满了遐想，随着年龄的增长，我觉得生活也充满着无数个多姿多彩的气泡，每个气泡都是一个故事每个气泡都包含着人生的喜怒哀乐，我也和大家一样，享受着生活中的泡泡。

It was wholly in the lower ice, but close against the upper, and was flattish, or perhaps slightly lenticular, with a rounded edge, a quarter of an inch deep by four inches in diameter; and I was surprised to find that directly under the bubble the ice was melted with great regularity in the form of a saucer reversed, to the height of five eighths of an inch in the middle, leaving a thin partition there between the water and the bubble, hardly an eighth of an inch thick; and in many places the small bubbles in this partition had burst out downward,and probably there was no ice at all under the largest bubbles,which were a foot in diameter.

在气泡之下和周围已经结了一层新的冰，所以气泡是在两片冰的中间；它全部是在下层中间的，却又贴近上层，扁平的，也许有点像扁豆形，圆边，深四分之一英寸，直径四英寸；我惊奇地发现，就在气泡的下面，冰溶化得很有规则，像一只倒置的茶托，在中央八分之五英寸的高度，水和气泡之间有着一个薄薄的分界线，薄得还不到一英寸的八分之一，在许多地方，这分界线中的小气泡向下爆裂，也许在最大的直径一英尺的气泡底下完全是没有冰的。

The Activated Ploy-oxygen Aerator adopts magnetic engineering technology to send the oxygen of air which is gathered and activated by polyoxier to the mixing chamber of main engine under water, and the process of water and oxygen synthesization is finished rapidly by the use of magnetizer and activated oxygen enriched air under water, which has been cut into tiny air bubbles by the high-speed rotated propeller of the mixing chamber in the process of water and oxygen synthesization, which can increase the affinity of water and oxygen. When flow rate of water is more than the buoyancy force of the tiny air bubbles, it is difficult for the tiny air bubbles to float on water in short time and the tiny air bubbles can stay in water for longer time, which can increase the efficiency of water dissolving oxygen and make the power efficiency of the machine is greater than traditional aerator obviously.

聚氧活化曝气增氧机采用磁性工程技术，将空气中的氧经聚氧器聚集活化后送到水下主机的混合室，由水下的磁化器和活化富氧空气快捷完成水气合成程序，在水气合成过程中已被混合室内高速旋转的离心叶轮切割成微小气泡，这些随射流、射向水下方的小气泡，其动能消耗至零后，在水中的浮力作用下、开始缓慢上升，由于提高了水与氧亲合力的小气泡只靠浮力沿着螺旋型的曲线缓慢浮升，这些小气泡在短时间很难浮上水面，因此延长了小气泡在水中的停留时间和行走路程，大大提高水中溶解氧的效率，使该机的动力效率明显高于传统曝气装置。

The results show that, with the liquid viscosity increases, the small bubbles retain spherical shape well, while the large bubbles change gradually from the irregular ellipsoid to the form of spherical cap, the periodical oscillation and the bubble terminal velocity decreases.

结果表明，随着液相黏度的增加，小气泡均能呈良好球形，而大气泡则由类似椭球形的不规则形状逐渐向球帽形转变；气泡的周期性振荡趋于平缓，气泡上升终速度降低。

The reason that why bubbles grew and how the gas was released from undecomposed TiH_2 were stated. The merging of bubbles and formation of bubble-free laye...

结果表明：未分解的TiH2颗粒粘附在熔体内形成的较小气泡表面，即气/液相界面上；在恒温发泡过程中气泡壁上吸附的尚未分解的TiH2颗粒进一步分解并向气泡内释放气体，使气泡长大；相邻气泡壁上的TiH2局部浓度较高并集中释放气体，导致气泡壁破裂及气泡间的合并。

As the same section is concerned, near the bottom the maximum value of frequency appear within 1mm of bubble size, towards the water face this value tend to decrease, yet the corresponding size turns to increase; in the same time, the frequency is concentrated near the bottom and deconcentrated near the water face; under the experiment condition, the maximum frequency of the total section approximately appear at 0.5mm size; mean bubble size access 0 at bottom and increase acceleratively towards water face where tend to be infinite; total number increase during developing of aeration, and become steady when reach wholly developed area; on the same section, the total number in unit time tend to increase at first and decrease then, along the water depth.

对于同一断面，靠近槽底的测点气泡个数分布最大值出现在气泡尺寸小于1mm的范围内，朝水面方向各测点气泡个数分布最大值呈减小趋势，而其对应尺寸则呈现变大趋势；在靠近槽底，个数分布表现得比较集中，而在水面附近气泡个数分布曲线表现得低而平缓；实验条件下，整个断面上的气泡个数分布的最大值大体上出现在尺寸为0.5mm的地方；气泡平均尺寸在槽底处接近于0而朝水面方向迅速增大，且越接近掺气水流的水面，增加速度越快，最终趋于无穷大；气泡总数在掺气发展区内是沿程增加的，当掺气水流发展到一定程度后气泡总数就基本保持不变了；在同一断面上，各测点单位时间内的气泡总数随高度呈现出先增加后减小的趋势。

As prefigures possibly a saturation of the enhancement of bubble film.

散射光照度一定周期性的规律，说明随着航速的增大，尾流气泡幕逐渐增强，气泡幕中气泡密度、不同直径气泡分布等均随之变化，这可能预示着气泡幕的增强存在饱和度。

Bubble film builds up gradually,the thickness and distribution with diameters and etc change,along with the increasing of the speed of ship,based on the periodicity of scattered light illumination.As prefigures possibly a saturation of the enhancement of bubble film.

Bubbling temperature direct affect the diameter and the distribution of bubbles; Bubblier is a main factor which influence the bubble structure of foam glass. To select different bubblier results in different craft. To add stabilizer directs affect the melt viscosity, besides superficial expansion.

在泡沫玻璃烧结过程中，发泡温度(760～950℃)影响泡径及气泡的分布状态；发泡剂是影响泡沫玻璃制品泡孔结构的主要因素，发泡剂不同，发泡时间不同，则气泡的泡径和开闭口的情况就不同；在泡沫玻璃烧结过程中，稳泡剂的加入直接影响粘度，粘度过高气泡不易产生，粘度过低气泡极易逸出，两者都不利于产生所要求数量的气泡；另外，表面张力和配料中的水对发泡也有一定的影响。
