摘要
The Newtonian gravitational constant G is determined by means of the swing time method at the Cave Laboratory of Center for Gravitational Experiment of Huazhong University of Science and Technology. The result value of G is (6.669 0±0.001 6)×10 -11 m 3·kg -1 ·s -2 , which is consistent with the CODATA value of G obtained by Cohen and Taylor in 3σ .
