摘要：
A precision measurement of the gravitational constant G has been made using a beam balance. Special attention has been given to determining the calibration, the effect of a possible nonlinearity of the balance and the zero-point variation of the balance. The equipment, the measurements, and the analysis are described in detail. The value obtained for G is 6.674 252(109)(54)x10(-11) m(3) kg(-1) s(-2). The relative statistical and systematic uncertainties of this result are 16.3x10(-6) and 8.1x10(-6), respectively.
