| 摘 要： | 依据地震观测技术的基本原理和大量观测事实,给出统一的地震连续形变观测技术仪器的特性曲线,分析和解释其对“前兆”信息响应差异的根本原因.地震连续形变前兆仪器对地震及其前兆响应的差异是因为仪器的传递函数不同和特性所致;其前兆观测中的分钟值采样数据中发现的震颤异常波,只是真实信号的一种“混叠”或映射,难以反映真实的地面运动....

| Abstract: | In daily monitoring of seismic crustal deformation,we often found out that there are some abnormal microseisms in the tidal signals.These microseisms called abnormal tremor wave are observed by the broadband digital seismograph.This article reports a lot of the abnormal tremor waves recorded by DZW gravimeter and VS-1 tiltmeter in HUST seismic and tidal station.According to the principle of seismic measuring techniques and observations,we present a unified characteristic curve for seismic crustal deformatio... |
