1) toroidal bubble
环状气泡
2) bubble shape
气泡形状
1.
The comparison of the variation of bubble shape and volume during bubble growing process between the two kinds of solutions was made.
采用激光成像结合CCD摄像技术分别对牛顿及非牛顿流体(甘油和羧甲基纤维素钠水溶液)中的气泡生成行为进行了研究,对2种流体气泡生成过程中气泡形状和体积变化进行了比较。
2.
The results for single bubble show that, in low-viscosity liquids, the bubble shows large distortion and oscillation, the bubble shape changes from the spherical shape to the irregular ellipsoid and the bubble rising trajectory changes from a rectilinear path to a zigzag or spiral path as the bubble equivalent diameter increases.
对单个气泡的研究结果表明,在低黏度液体中,随着气泡直径的增加,气泡振荡形变剧烈,气泡形状由球形向类似椭球形的不规则形状转变,上升轨迹由直线形向之字形、螺旋形转变;在高黏度液体中,随气泡直径的增加,气泡形状逐渐由球形向呈球帽形转变,气泡的周期性振荡趋于平缓,纵横比增大,气泡上升速度降低。
3.

针对Eo数从O(0)～O(2),Mo数从O(11)～O(2)的流动范围,重点研究了上升气泡的形状特性,并与经典的气泡形状图谱进行了比较。
4) bubble flow
气泡状流动
5) spherical cap bubble
球帽状气泡
6) bubble flow
泡状流，气泡状流动

表面气泡
skin hole
b iaomian qiPao表面气泡(skin hole)钢锭表面上一些开口的孔眼。是钢中气体析出于钢锭表皮而形成的;钢锭模壁潮湿，或使用的保护渣潮湿，在浇注时蒸发出气体，也会使钢锭形成表面气泡。它会使轧材出现深口、裂痕、甚至海绵面等缺陷。其防止措施主要是降低钢液气体含量，保持锭模和保护渣干操。 (汪建农)
