| 摘 要： | 在周期法测量万有引力常数G的实验中,扭秤所处环境的磁场分布非常复杂.本文通过一定的理论模型,计算了磁场对扭秤的作用力矩.计算结果显示,扭秤受到的力矩与磁场的梯度和恒定磁场的大小有关,且力矩包括恒定的和随时间周期变化的两部分.

| Abstract: | In the time-of-swing method of measuring G,the distributions of the ambient magnetic are very complicated.In this paper,the magnetic field on the torque of torsion balance is calculated through a certain theoretical model.The computation results show that the magnetic torque of torsion balance is related to the magnetic field gradient and the size of constant magnetic field.And the magnetic torque includes two parts,the constant torque and with time periodically changing torque. |
