摘要
对我国20世纪90年代以来地震流动重力观测资料质量和精度统计分析结果表明:流动重力工作状态稳定、观测资料质量良好,观测资料的单位权中误差和点值中误差均达到或接近10×10-8m s-2,已完全具备检测因构造活动等因素引起的重力场非潮汐变化的能力。
The quality and the accuracy of repeated gravimetry data since 1990 are analyzed. The results shows that the running state is stable and the quality of the data is good, both of the mean squares errors with unit weight and gravity value at each point of the data reach or closes to 10 × 10^-8ms^-2, thus the repeated gravimetry has already had the ability to detect the non-tidal gravity changes caused by tectonic activities.
