摘要

针对现有的密度检测方法存在的精度低或操作计算过程繁琐的缺点，结合磁-阿基米德悬浮技术，提出了一种抗磁性物质密度的精确测量方法。该方法应用的磁悬浮测量装置可以保证被测样品在装置中达到稳定悬浮，并且在其他实验条件一定的情况下，样品悬浮高度仅与样品本身密度相关。建立了样品悬浮高度与样品密度的关系函数，可以由样品在装置中悬浮高度算出样品密度。通过拟合一组标准密度球在给定实验条件下的悬浮高度，得出了可在任意条件下根据样品悬浮高度进行密度计算的计算公式，并通过多组实验对公式的准确性进行了验证。还通过对几种高分子材料的实验，与传统浮力法进行了比对。实验及分析结果显示，该测量装置操作简便，具有很高的测量精度，可以达到0.0025 g/cm

，有很大的应用发展空间。相较于传统方法，该方法对小尺寸样品密度测量具有更高的测量精度。

Abstract

Aiming at disadvantages of low accuracy or complicated operation calculation process of the existing density detection method

and combined with technology of magnetism-Archimedes suspension

a kind of accurate measurement method for density of diamagnetic material has been proposed. Measuring equipment for magnetic suspension used by this method may guarantee that sample tested could reach stable suspension

and the suspension height of sample has correlation with density of sample itself under the condition where other experimental conditions are certain. The relation function between suspension height of sample and density of sample has been established

and the density of sample may be calculated through suspension height of sample in the equipment. By fitting a set of suspension height of standard density sphere under experimental conditions given

the calculation formula has been obtained

in which density could be calculated under arbitrary conditions according to suspension height of sample

and the accuracy of formula has been verified through many experiments. In addition

experiments with several kinds of high polymer materials are contrasted with traditional buoyancy methods. Experiment and analysis results show that:this measuring equipment has easy and simple operation

relatively high measurement accuracy (reaching 0.0025g/cm

) and great application and development space. Compared with traditional method

this method has higher measurement accuracy for density measurement of sample with small size.
