摘　　要：高速摄像是先进的图形显示测量技术,在各种实验研究中都有广泛应用.本文针对水口吹气条件下板坯结晶器水模内的气泡行为进行了测定,得到了直观的准确的气泡运动数据.结果表明,上回流区内绝大多数气泡的运动轨迹是类似的,呈现类似"L"的形状.气泡以一种近似匀速运动的方式完成上浮过程.High speed video is a kind of advanced technique for graphical display and measurement, which is widely applied in much experimental research. In this paper, the movement of bubbles was investigated in a water model of slab continuous casting mould with argon injection through submerged entry nozzle, and more visualized and accurate experimental data of bubble movement has been obtained. The results show that the trajectories of most bubbles in the upper vortex are similar to ＂L＂ shape. The bubbles ascend approximately with constant velocity.
