中文摘要：

该文用高速摄影对稳定状态静止水下气泡生成和运动形态进行分析,详细讨论了气泡的动力理论特性。运用数字图像处理技术,对高速摄影图片的像素进行灰度归一化处理及二进制转化,通过对气泡质心运动的跟踪来获得其运动特性,并对所得数据进行编程处理分析,得到气泡运动轨迹。同时,结合Stokes和卡门涡理论分析,得到稳定状态下不同尺寸单个气泡的速度变化规律,运动轨迹规律等各种运动特性,并将实验结果与理论进行比较分析来判断其可行性。对稳定状态下的气泡研究可以为更深入的研究有扰动下的气泡复杂性提供基础和依据。

英文摘要：

In this article, high speed photograph equipment was used to take photos for the bubbles in the calm water, which were under the steady conditions and can describe the dynamic property of the bubbles. According to image process technology, photo elements were converted into binary normal forms to trace the bubble’s barycenter to get its motion characteristic. Combining with Stokes and Karman Vortex theory, the characteristic of ascendant motion of bubbles with different size was obtained through programming...
