【摘要】 为了适应地震研究中长期、连续地计算潮汐导纳的需要,本文在维尼狄可夫调和分析的基础上引入卡尔曼滤波理论,导出了计算潮汐导纳的递推方法。该法具有优于维尼狄可夫法的精度、计算简单、采样密等优点,且能自动判别资料中突跳等短期异常,因此不需要作资料的预处理。应用本方法对泰安台石英倾斜仪观测资料进行了计算,获得了较为满意的结果。更多还原

【Abstract】 In order to meet the needs of calculating tidal admittances continually over a long period of time in seismology, based on Venedikov harmonic analysis, we derive a recurrence method by the application of Kalman filtering theory. This method has many advantages, such as higher accuracy,simple calculation,and denser sample than that of Venedikov method. In addition,the short-term anomalies of data, such as the jump of observed data, distortion of tidal waves, can be judged and rejected automatically in the filtering process. So, no pretreatment of data is needed before calculating tidal admittances. The satisfactory results calculated by this method are got in the practical calculation with the observed data of Taian station.更多还原
