- 摘要:
- 2008年5月12日发生的汶川80级巨大地震中，北京地区的一些流体观测仪器记录到了不同程度的同震响应。为了进一步深入研究该次强烈地震对北京地区未来地震活动趋势的影响，系统搜集、整理归纳了该次巨大地震引发的北京地区流体观测仪器记录到的同震响应信息，将北京地区的流体同震现象进行概括，然后分析了数字化流体分钟值观测资料同震效应的表现形态及其变化特征，验证了新安装的一些数字化流体观测仪器的可靠性、灵敏性，对相关流体观测仪器可能存在的一些问题进行了讨论。
On May 12，2008， a MS 8 huge earthquake occurred in Wenchuan， Sichuan Province. During this earthquake，coseismic response of some liquid observations are recorded in varying degree by the apparatus in Beijing. In order to studying the influence of the Wenchuan earthquake to the future seismic activity trend in Beijing area， we collected and summarized simultaneous shock responses of Wenchuan earthquake recorded by liquid observation apparatus in Beijing， analyzed the form and change characteristics of liquid digital minute observation data， the results show that each kind of liquid observation recorded different amplitude vibrate wave， and the record ability of different device is distinct from each other. The reliability and sensitivity of digital apparatus in Beijing area are tested. Some problems of liquid observation apparatus and their data are discussed.
