摘要
对漳州地震台SS-Y型伸缩仪日常观测资料中出现的多种短时畸变,利用Matlab软件进行谱分析和滤波处理,总结各种干扰表现形式,以便更好识别非地震前兆因素干扰,为地震研究服务。
A variety of short-term distortion occurred in daily observation data of SS-Y expansion instrument at Zhangzhou Seismic Station. With Matlab software, spectrum analysis and filtering are adopted to data analysis. Through an analysis of the results, the various types of interference factors in extensometer observation are summarized for better identification of non-seismic precursory factors.
