| 摘 要： | 本文介绍了在海边进行的为期32 d的KSS31M海洋重力仪静态观测结果，试验数据表明：KSS31M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0.1×10-5 m·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1.7×10-5 m·s-2；重力仪的月漂移小于1.7×10-5 m·s-2.

| Abstract: | This paper introduces the static measurement results of KSS31M marine gravity-meter at coast and declares the wrong conclusions of Luan Xiwu (2004). The data show that the KSS31M 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. |
