摘要: A new determination of the numerical value gravitational constant G was carried out by means an apparatus consisting a fibreless torsion balance which buoyancy floater in liquid; angular deflection compensated with aid control loop and electrostatic torque transmitter; reacting bodies were cylinders. The result obtained for differs from CODATA about +6 × 10-3 relative value. No dependence on materials or distance between cylinders found. is described, methods evaluation results are reported, possible sources errors discussed.
