摘　　要：磁流变液在工程应用中的优势已经在诸多领域得以体现,稳定性要求也随着应用环境的不同而变化。其稳定性主要受基液黏度、磁性颗粒体积分数以及所添加的活性剂等因素的影响。孔口出流是液压和气压传动中应用十分广泛的流动形式,磁流变液的孔口出流分析对于节流调速和伺服系统工作原理具有重要的作用。The MR fluid has been widely applied in the engineering field. The requirements of its stability are changed with dif- ferent application environments. This stability is mainly affected by the base fluid viscosity, the magnetic particle volume fraction and the active agent added. Orifice flow has been considered as a widely used flow pattern of hydraulic and pneumatic transmission, so that the analyses of orifice flow for the MR fluid are important for the throttle speed control and servo system.
