利用扭摆对牛顿平方反比定律在亚毫米范围内进行了零位实验验证。在预期信号和用于校准的引力扭矩的双重调制下，我们的数据以95%的置信度得出结论，即没有观察到新的力，并且对于两个尺寸相同的R*<；47微米的压缩额外空间维度，任何引力强度Yukawa力(|α|>；或=1)必须具有长度标尺lambdaor=2.8TeV/c2。
A null experimental test of the Newtonian inverse-square law at submillimeter range using a torsion pendulum was presented. Under the dual modulations of both the expected signal and the gravitational torque for calibration, our data concluded with 95% confidence that no new forces were observed and any gravitational-strength Yukawa forces (|alpha|>or=1) must have a length scale lambdaor=2.8 TeV/c2 for the two compactified extra space dimensions with the same size R*<47 microm.
