摘要(Abstract):

推导了旋转轴液体密封中液-液界面由于相对运动引起的切应力,从相对速度角度对液体动密封界面稳定性问题进行了研究,并对结构进行了改进,将磁流体界面的稳定性问题转化为静态扩散处理。
The stress has been deduced which is caused by the relatively moving of interface.Based on the relative speed,the structure of magnetic pole has been improved.The stable interface has been simplified to the dealing of static diffusing action.

关键词(KeyWords): 磁流体;液体密封;界面稳定性
