摘　　要：磁流体水平流速与垂直波动幅值都会影响电流效率。在电解质熔体与阴极铝液相接触界面上,熔体垂直振荡与水平流动相比较,垂直波动状态有更大的接触面积,更快的相对运动速度和更短的氧化层距离。因而垂直波动状态对电流效率下降有更严重的影响。Both horizontal velocity and vertical oscillations of MHD have influence on the current efficiency. On the contacting surface between bath melt and cathode liquid aluminum, comparing vertical oscillations with horizontal flow, there were larger contacting surface, faster relative velocity and shorter oxide layer distance under the vertical oscillations, so the vertical oscillations has more serious influence on the current efficiency.

关 键 词：溶解面积 相对流速 氧化层距离
