【摘要】 用维尼迪科夫(Vinedikov)调和分析方法,计算了2008年1月1日至2010年12月31日高台地震台重力潮汐观测资料,获得几个主要潮波的重力潮汐参数。对日均值采用最小二乘拟合法,分析了非潮汐重力变化信息。基于一元线性回归,分析了气压对重力潮汐观测的影响。结果表明:高台台重力观测精度较高,O1、M2波潮汐因子变化稳定在1‰之内,与国家重力台网中心结果基本一致。更多还原

【Abstract】 Basing on the gravity tide observation data recorded by Gaotai Seismic Station from Jan.1,2008 to Dec.31,2010,we obtained the gravity tidal parameters of several main tidal waves by Vinedikov harmonic analysis method.Then we analyzed the non-tidal gravity variation of daily mean value by least-squares fitting method and the effects of atmospheric pressure on gravity tide observations basing on one-dimensional linear regression.The results showed that the precision of gravity observation at Gaotai Station is high,the variation of tidal factors of O1,M2 waves stabilized at 1‰,which is consistent with that in Gravity Network Center of China.更多还原
