摘要: 许多理论模型预言牛顿引力反平方定律在近距离下将发生偏离.本文简要介绍了牛顿反平方定律的实验检验现状,给出了利用精密扭秤技术检验近距离反平方定律的实验原理和实验结果,分析了扭秤实验的热噪声和灵敏度.

关键词: 牛顿反平方定律, 精密扭秤

Abstract: A number of theoretical speculations predict that the gravitational interaction could display fundamentally new behavior in short-range regime.This paper presented the experimental principle for test of gravitational inverse-square-law,and reported our experiment result on test of gravitational inverse-square-law with a torsion pendulum,as well as the thermal noise and sensitivity analysis.

Key words: Newtonian inverse-square law, torsion pendulum
