【摘要】 通过对泰安地震台水平摆20多年光记录和8年数字化记录资料的整理和统计分析,得出泰安台水平摆固体潮年变曲线的规律,将其变化趋势作为一个基本模型,作为将来资料分析的依据,同时将光记录与数字记录年变趋势做对比分析,初步探讨同一峒室同一仪器墩上的这2个仪器趋势变化不尽相同的原因。更多还原

【Abstract】 On basis of statistical analysis on over 20 years’ optical recording data and 8 years digital data of horizontal pendulum at TaiAn reference seismic station,a annual variation law of earth tide is obtained,which is used as a basic model for further data analysis.Meanwhile,the reason why the two instruments which are lied on the same instrument frusta showing different changing trends is discussed through comparison of annual change curves of optical recording and digital recording.更多还原
