摘要
应用S变换,对比分析湖州地震台秒采样定点形变观测到新疆皮山县6.5级地震的频谱动态演化特征,VP倾斜仪和JCZ地震计记录的地震波较为相似,不同的震相有不同的周期,有显著的震相特征,但SSQ倾斜仪不同震相的周期没有显著的差异性。
Based on the second sampling deformation observational data of the Pishan M 6.5 in Xinjiang recorded by Huzhou seismological station,the S-transformation is used to compare and analyze the spectral dynamic characteristics of data. The VP inclinometer and the JCZ seismometer recorded the similar waveform, which have significant phase characteristics,different phases have different periods. But there is no significant difference in the period of different phases recorded by the SSQ inclinometer.
