It can be neglected that rise velocity of gas bubble is very small in melt.

气泡在熔体中的上升速度很小，可以忽略。

A model for the rise velocity of a single deformed bubble in liquid solid fluidized beds was formulated, based on the analysis of the forces acting on a bubble.

以气泡在上升运动过程中的受力分析为基础，建立了描述单个变形气泡在液-固流化床中上升速度的理论模型。

The influences of the superficial gas velocity, solid holdup and flowing resistance on gas holdup, bubble size, bubble rise velocity and liquid velocity were systematically studied.

考察了表观气速、固含率和流动阻力对气含率、气泡大小、气泡上升速度和液速的影响。
