中文摘要：

采用引潮势和海潮潮族作为输入函数，对北京实测的重力潮汐进行了响应分析，将频率相同的引潮力产生的重力天文（引力）潮和海洋潮汐负荷效应产生的重力负荷潮分离开．再对重力天文潮和负荷潮进行调和分析，得到北京重力天文潮和负荷潮的平均变幅分别为121．5和7．5微伽．海洋潮汐的负荷影响为北京重力天文潮的6．2％．

英文摘要：

Using tide producing potential and the ocean tidal species as the input function, the observational gravity tidal data in one year at the Beijing station were analysed by the response method. The gravity astronomical tide and the load tide with the same frequency were separated, and then they were analysed by the harmonic method. Results show that the average tide range of the gravity astronomical tide and the load tide are 121. 5 and 7. 5 uGal respectively, and the loading effect is 6.2% of the gravity astronomical tide at the Beijing station.
