摘　　要：采取本底曲线扣除措施,扣除扭摆吊丝弹性恢复力矩非线性变化和环境温度变化产生的系统误差,可将扭摆的测量精度提高到9.6×10^(-3),周期的最大相对起伏减小到9.4×10^(-3)。The period drift of a torsion pendulum depends on the change of environment temperature and the non-linear property of spring restoring moment of suspending wire of the torsion pendulum. To reduce this system error, a method of deducting background curve has been adopted. As a results, the measurement precision of the torsion pendulum, 9.6×10^(-8) and the maximum relative fluctuation of the period, 9.4×10^(-8) have been reached.
