不同采样率水位同震响应能力及其特征分析

摘要

Records of coseismic response that recorded by the same instrument but with different sampling ration are analyzed.It is found that there are mach difference not only in morphology but also in capabilities and response amplitude.Second sampling rate data can better record coseismic response.In order to record the true,complete and reliable coseismic response,observation instruments should make improvements in sampling ratio,data storage capacity,GPS time,the trigger threshold,the reader way of the hour and minute value.At last,we indicate that coseismic response analysis will be a breakthrough research direction to earthquake analysis and prediction in the future.%分析同种仪器不同采样率水位资料同震响应记录情况,发现存在很大差异,不但形态上明显不同,响应能力及响应幅度上也差别很大.在此基础上认为,秒采样率数据能更好记录同震响应.指出,为了记录到真实完整可靠的同震响应,观测仪器应在采样率、数据存储容量、GPS授时、触发阈值、时值及分钟值取值方式等方面作改进.最后指出,同震响应分析可能是今后地震分析预报有所突破的一个研究方向.
