涉县地震台数字化观测与模拟观测资料对比研究

CONTRASTIVE ANALYSIS ON THE DIGITAL AND ANALOG DATA OF CRUSTAL DEFORMATION IN SHEXIAN SEISMIC STATION

摘要: 介绍了涉县地震台站基本现状及其形变数字化仪器改造情况,并从长期趋势、短期趋势和固体潮形态变化等方面对涉县台形变模拟观测和数字化观测资料进行形态对比,对数模两种观测资料的连续性、稳定性、一致性和固体潮观测精度进行分析研究,得出数字化资料总体评价结论。针对涉县数字化资料存在的问题和解决办法提出具体建议。

Abstract: The basic situation and digital reconstruction of Shexian seismic station are introduced and digital data are compared with analog data in permanent trend,short-term trend and the change of solid tide modality.Contrastive analysis on the digital and analog data in the field of continuity,stabilization and the precision of the solid tide observation and gained the estimate of the digital data is done.According to existing problems,concrete suggestions are proposed.
