摘要
研究了银川台洞温对重力观测的影响,结果表明,重力非潮汐变化与洞温变化显著相关。提出了重力测量对洞温的改正模型。经验证,观测资料经模型改正后,潮汐参数的精度有了显著提高。
In this paper,we analyse the influence of the temperature in cave on gravity observations at Yinchuan station. It shows high correlation between the non-tidal gravity and the temperature. A reasonable correction model has been obtained, and the accuracy of tidal parameter is raisedthan ever after applying the model.
