| 摘 要： | 使用CCD相机连续跟踪气泡的运动过程，将拍摄的数字图像进行处理，从而得到气泡沿床层高度方向形状、尺寸的变化。根据拍摄的连续图像，与标定值比较可以确定气泡在床中的实际位置，从而得到气泡的运动轨迹。

| Abstract: | The moving progress of bubbles is continuously traced by CCD (Charge Coupled Device) camer-a, the digital photographs are captured when the experiment is dealt with using image processing technology , then the shape and scale of bubbles along the height can be obtained. In terms of those continuous photographs, and comparing with the calibration value , the real situation of bubbles in the bed can be determined , then the trajectories of bubbles can be obtained. |
