【摘要】 本文介绍了在海边进行的为期32 d的KSS31 M海洋重力仪静态观测结果,试验数据表明:KSS31 M海洋重力仪可以清晰地记录重力固体潮理论值的变化,精度优于0.1×10-5m.s-2(即常用的0.1 mGal);潮汐海浪对重力仪观测数据产生了很大的影响,重力观测值表现出曲线变化特征,周期与海潮周期一致,变化幅度高达1.7×10-5m.s-2;重力仪的月漂移小于1.7×10-5m.s-2.更多还原

【Abstract】 This paper introduces the static measurement results of KSS31 M marine gravity-meter at coast and declares the wrong conclusions of Luan Xiwu(2004).The data show that the KSS31 M marine gravity-meter clearly recorded the calculated solid earth tide gravity variation,indicating the gravity-meter has a resolution better than 0.1×10-5 m·s-2.The oceanic tide made a significant contribution to the measured gravity variation,so that the gravity variation is a curve instead of common line type.The cycle of the curve type gravity variation is consistent with that of the oceanic tide.The amplitude of the gravity curve is up to 1.7×10-5 m·s-2.The gravity drift rate is less than 1.7×10-5 m·s-2 one month.更多还原
