摘要
针对湟源地震台钻孔应变观测数据的实际情况,并根据本台仪器所处环境,受干扰情况,运用连续小波变换、二进小波变换、离散小波变换,多分辨分析、Symlets分解与重构算法等方法,对湟源地震台钻孔应变数据进行分析研究,结果表明该方法能够有效地将数据变化、突跳和地震同震效应从原数据中突显出来,并且能够根据不同的需要突显出有用的信息,更好地为地震预报服务。
According to the environment influence of the equipment＇ s location and other external interferences, the 4 - component borehole strainmeter data of Huangyuan seismic station are analyzed by the continuous wavelet transform, dyadic wavelet transform, discrete wavelet transform, multi-resolution analysis and Symlets decomposition and reconstruction algorithm methods, and the results show these methods can effectivelypresent the features of the data changing, sudden jumpscan supply better service fbr earthquake prediction.
