【摘要】 本文对拉科斯特G型重力仪特性、零漂特征、格值误差、测量精度以及《地震重力重复测量规范》中有关自差互差等问题作了讨论。认为:拉科斯特重力仪具有性能稳定,零漂小,观测精度高的优点,各仪器之间的系统误差不明显,格值误差极小;规范中规定的30×10^-8m/s²自差和3S×10^-8m/s²互差偏大。建议改为20×10^-8m/s²和25×10^-8m/s²为宜。更多还原

【Abstract】 In this paper, the instrument characteristic, drift feature and scale error are discussed, and the self-difference and mutual-differenee stipulated by 《The Canon of repeated seismological gravity measurement》are studied. The results are abtained as follows:1. LCR G gravimeter is a kind of stable instrument with small drift and high observed accuracy.2. The systematic errors among gravimeters is not significant and the scale error is smaller as well.3. The self-defference(30×10^-8m/s²) and mutual-difference (35×10^-8m/s²) in the canon is a little larger.We think that the better values are 20×10^-8m/s² and 25×10^-8m/s².更多还原
