| 摘 要： | 对山东泰安地震台数字化水平摆10年的观测资料中的典型畸变现象进行了分类,具体为:1)大幅度漂移,趋势性改变;2)单日固体潮畸变;3)多日固体潮畸变伴频繁掉格;4)频繁掉格,固体潮无明显畸变。NS分量畸变以趋势改变、固体潮升降变化为主,EW分量畸变以频繁掉格为主。映震能力:对震中距2 000~5 000 km大于7级以上的地震有反应,甚至远于5 000 km的极远震也有为数不少的震前畸变出现。

| Abstract: | The observations of digital horizontal pendulum of Taian seismostation for 10 years was systematically summarized.After excluding disturbance the typical variation of recorded data is classified and analysed.Basically,there are four types of variation as follows: 1) wide shift,trend change;2)earth tide distortion of single day;3) multi-day earth tide distortion accompanied with frequent zero-drift;4) frequent zero-drift without obvious variation of earth tide.Trend change and earth tide alteration dominate ... |
