| 摘 要： | 以具有机电耦合效应的磁性粒子浓悬浮溶液体系为例，讨论微米级粒子在悬浮体系中的沉降稳定性及其表征方法。实验结果表明，在微米级磁性粒子浓悬浮体系中加入一定量纳米粒子，不但能增强其磁流变效应，而且使微米粒子的沉降稳定性显著增加。后者类似结果也适用于具有电流变效应的其它浓悬浮溶体系。 |

| Abstract: | In the present paper, the sedimentation stability and characterization method of the dense magnetic suspension system with mechanics-electricity coupling effect are discussed by means of chemical analysis. The experiments showed that the sedimentation stability of the suspension system dispersed with micron magnetic particles could be greatly improved by adding proper amounts of nano-scale particles. This result is the same as the sedimentation stability of other dense micron particle suspension systems with electrorheological effect. Meanwhile, the shear stress of magnetic dense suspensions varied evidently with the added amounts of nano-scale particles. |
| Keywords: | dense suspension system stability of sedimentation characterization of sedimentation stability |
