| 摘 要： | 通过对银川台重力观测资料进行差分变化对比，与理论固体潮及室温变化进行对比分析，阐述了2007年台站重力观测山洞改造期间引起重力变化的主要因素。研究结果表明，山洞改造对重力观测的直接影响不显著，引起资料内在精度下降的主要原因是改造时保温措施不当，引起洞温迅速变化，继而影响重力观测。

| Abstract: | By contrasting the difference change of gravity observation data of Yinchuan station,and contrasting and analyzing the theory solid tide and the room temperature change,I elaborated on main factors of gravity change caused by gravity observation cavern reconstruct of this station in 2007.The research result showed that it is not remarkable that the cavern reconstruct caused direct the gravity observation.The main reason of intrinsic precision drop is that the heat preservation measure is improper in cavern reconstruct.It causes the cavern temperature to ascend rapidly.Then it effected the gravity observation. |
