Direct observation of the formation of bubbles in molten aluminum was carried out by using X-ray imaging technology. The formation process and the levitation process of bubbles from the vertical pipe were observed. The hirizontal pipe, however, the bubble wetted the pipe and wall. It is necessary to opitimize the boudary condition for bubbles formation.

利用X射线成像技术对铝液中气泡的形成过程进行了直接观察。观察了垂直管内气泡的形成过程和悬浮过程。然而，在hirizavian管道中，气泡润湿了管道和壁。气泡形成的边界条件必须优化。
