Experiments measuring the Newtonian gravitational constant G can offer uniquely sensitive probes of the test of the gravitational inverse-square law. An analysis of the non-Newtonian effect in two independent experiments measuring G is presented, which permits a test of the 1/r^{2} law at the centimeter range. This work establishes the strongest bound on the magnitude α of Yukawa-type deviations from Newtonian gravity in the range of 5-500 mm and improves the previous bounds by up to a factor of 7 at the length range of 60-100 mm.
测量牛顿引力常数G的实验能够为引力平方反比定律的检验提供独特的高灵敏度探针。本文对两个独立测量G的实验中的非牛顿效应进行了分析,从而能够在厘米尺度上对1/r²定律进行检验。这项工作确定了在5-500毫米范围内汤川型与牛顿引力偏差的幅度α的最严格限制,并在60-100毫米的长度范围内将先前的限制提高了多达7倍。
