摘　　要：通过对铝电解槽内熔体的稳态及瞬态运动分析,提出磁流体稳定性与稳态流场是两个截然不同的概念。稳态洛伦兹力作用产生旋转流动。MHD稳定性则是指在平衡条件下,外界的扰动时,铝电解槽恢复平衡状态的能力。本文还介绍了垂直磁场对MHD稳定性的影响及分析方法。By means of analyzing the steady and transient movement of the melt in aluminum reduction cells,it is pointed out that the steady flow field and the MHD stability of reduction ceils is difference. The steady flow is the motion driving by steady Lorentzforee. Under equilibrium situation, MHD stability is the capability to damping the disturbance and wave motion. The paper also introduces the effects of vertical magnetic field on MHD stability.
