摘要：

为了克服现有磁悬浮密度测量方法存在测量范围小（0.8~2.3 g/cm3）的缺点，提出全新的针对抗磁性高密度物质的密度测量方法.该方法将高密度物质通过一定长度的细线悬挂，并将高密度物质置于水平放置的磁悬浮装置中，高密度物质在重力、浮力、拉力和磁力的综合作用下产生横向悬浮位移.在分析顺磁溶液中物质受力情况的基础上，建立物质横向悬浮位移与密度的关联函数关系，基于该函数关系实现高密度物质密度的精确测量.实验结果表明，采用该方法可以测量小尺寸高密度样品（如铜、铝和玻璃等）的密度，测量精度为0.028~0.165 g/cm3.随着样品密度的增加，测量偏差呈现增大的趋势.
Abstract:

A novel density measurement method for diamagnetic high-density materials was proposed in order to solve the problem that the existing density measurement method through magnetic levitation has a disadvantage of low measurement range (0.8-2.3 g/cm3). A high-density sample was hanged by a string at a certain length, and the sample was put into a transverse magnetic levitation device. In the transverse magnetic levitation device, the sample would generate a transverse levitation displacement under the resultant force of gravity, buoyancy, tensile force and magnetic force. A mathematic function between the transverse levitation displacement and the density of the sample was established based on the analysis of the forces for the sample in paramagnetic fluids. The density of the high-density sample can be obtained according to the mathematic function. Experimental results show that the proposed method can measure the densities of small-sized high-density samples (such as copper, aluminum, and glass, etc), and the density measurement accuracy can be up to 0.028-0.165 g/cm3. The accuracy of density measurement decreased as the sample's density increased.
