摘要: 在扭摆法测量引力常量的基础上,提出利用激光干涉法测扭转偏角,并采用磁感应力来消减周围环境的噪声干扰,能使引力常量G的测量精度有很大提高.

关键词: 引力常量, 激光干涉法, 磁场消振

Abstract: Based on traditional torsion balance gravitation constant G is mesured and laser interference is used measure deflect angle. To eliminate environment effect, magnetic field is used.

Key words: gravitation constant, laser interference, eliminate vibation by magnetic field
