【摘要】 采用基于EMD自动提取算法及地震触发判断算法实现对台站连续重力数据的潮汐、尖峰、台阶、仪器漂移和趋势性变化的消除,达到连续重力非潮汐信息的自动分离提取。研究实例表明,该算法可实现对重力台站资料的自动处理,适于对大量台站连续重力观测资料进行批量化处理,快捷地提取非潮汐变化信息。更多还原

【Abstract】 The effect of tidal,peak,step,instrument drift and trend from the continuous tidal gravity data was removed by using the automatic extraction algorithm based on EMD and earthquake triggering algorithm,and achieved successfully the automatic extraction of tidal and non-tidal gravitational information.The examples show that the algorithm greatly reduces the manual work and it may be used for batch processing and quickly extracting the information of non-tidal changes of a large number of stations.更多还原
