A phenomenological study on the fitting method in real time has been done, and the method was applied to process and analyze the extensive data of a long period torsion pendulum used to determine Newtonian gravitational constant G. The result shows that the fitting method in real time is effective to determine the period of a torsion pendulum with a relative precision of 10-5 orders. 相似文献

在华中理工大学引力实验中心的山洞实验室进行了扭秤周期法测量万有引力常数G的实验 .初步的实验结果为G =( 6 .6 6 90± 0 .0 0 1 6 )× 1 0 -11m3 ·kg-1·s-2 ,其相对精度为 240× 1 0 -6.这一结果在3σ范围内与1986年Cohen和Taylor给出的平均值相吻合 . 相似文献
