摘　　要：报导在磁性粗粒子浓悬浮液体系中，加入非磁性粒子对磁流变液性能的增强效应，以及增加体系的沉降稳定性，并简要讨论了这些添加物对磁流变液“相变”的影响。In the present paper, it is reported that magnetorheological fluids effect were enhanced when non-magnetic nanosize particles were added to suspensions of concentrated micron particles, and sedimentation of the suspensions was improved by nanosize particles. The structure formation of solidified MR suspensions containing additives was tried to discuss.
