| 摘 要： | 利用精密扭秤测量了抗磁性物质铜与外磁场的相互作用，其基本思想是充分利用精密扭秤对弱力的高灵敏度，从而可极大地降低传统方法中对外磁场强度的要求．初步的实验结果证实了这一方法的可行性．

| Abstract: | The interaction between diamagnetic material copper and external magnetic field is measured by means of a precision torsion balance.Because of the high sensitivity of torsion balance for weak force in this methed,and so the magnitude of magnetic field can be greatly reduced in comparision with the traditional methods. Primary experimental result shows the feasibility of this method. |
