摘要
分析了 LCR-G 型重力仪周期误差的产生机制,讨论了周期误差标定的基本原理和方法,结合 LCR-G920和 LCR-G922在灵山重力基线场上的3次标定,对 LCR-G 型重力仪的周期误差进行了较为深入的研究,得出了一些有益的结论。
In this paper,the mechanism of periodic errors of Lacoste and Romberg (LCR)G gravity meters is analysed.The principles and methods of calibration of pe- riodic errors are also discussed.By using the three terms of calibration observations of LCR-G920 and LCR-G922,the further study on periodic errors of LCR-G gravity meters is taken,and some conclusions are reached.
