丹东地震台数字形变自然干扰因素分析

Analysis of the Natural Disturbance Factors of the Digital Deformation at Dandong Seismic Station

针对丹东地震台数字形变DSQ水管仪、SS-Y伸缩仪观测过程中长期存在的自然干扰现象进行整理研究,对其产生的机理和产出的数据形态分析,为快速、准确的判别自然干扰与前兆异常提供科学的参考。

The natural interference phenomenon was studied in this paper,which has been existed for a long time in the observation process of digital deformation DSQ water tube instrument and SS-Y extensometer at Dandong seismic station.The mechanism of its production and the morphology output data were analyzed,which would provide a scientific reference for the rapid and accurate discrimination of natural disturbances and precursory anomalies.
