摘要：

This paper describes the improvements that have been made to our measurement of the Newtonian gravitational constant (G) since our last published value of G in 1995. As a result of a new measurement of G made with the improved apparatus, we have discovered some second-order corrections that were omitted from the previous measurement. New values for G are presented; both from the latest measurement and a recalculated value from our previous measurement. Our latest values are G = 6.6742(7) x 10(-11) m(3) k(-1) s(-2) for the most recent measurement and G = 6.6746(10) x 10(-11) m(3) kg(-1) s(-2) for the recalculated 1995 value. These two values agree to within their uncertainties.
