摘　　要：利用自制的磁性液体研制出测量固、液两相胶体溶液磁性液体表现密度的测量装置并给出了测量方法和测量原理 .该装置既能测量磁性液体中不同液层的表观密度 ,也能测量磁性液体中某点的表观密度随磁场变化的规律.Using self-developed magnetic fluid, the apparatus of measuring apparent density of a two-phase colloid magnetic fluid (both in solid and liquid phase) is designed, and its measuring method and theory are introduced. The apparatus can not only measure apparent density in different magnetic liquid layer, but also measure the rule of apparent density change with magnetic field in magnetic fluid.
