摘要
针对所使用的两种类型不同的相对重力仪在相同的时间段、相同的地点的3次不同的动、静态观测试验,并对所得的观测试验数据进行了相关的计算和性能分析,结果表明:LCR-G、CG-5型两种类型仪器的动态观测精度都优于30×10-8 m/s2,符合实际测量要求;而且动、静态的零漂率很小且均成线性;两种类型仪器一致性观测精度高,可在一些项目的野外施工中可以混合使用。
Two different types of gravimeter were used in three different dynamic and static experimentsat the same time and in the same place, and the related processing and analysis of the observation data showed that the dynamic observation accuracy of two types of gravimeters, LCR-G and CG-5, were better than 30 × 10-8m/s2, in accordance with the requirements of the actual measurement. And the static and dynamic zero drift rate was very small and all linear. Two types of instruments consistent observation accuracy, could be used in the field construction of some projects.
