| 摘 要： | 以山西省测震台网部分台站使用的地震计为研究对象,选取一段时间的脉冲标定波形数据进行计算,根据脉冲标定处理结果分析得出地震计工作周期和阻尼变化的特点及原因,结合测震台网运行与维护实际工作经验,提出了检测地震计工作状态的思路和方法。实践证明,采用定期检测地震记周期和阻尼的变化可以在一定程度上反映出测震台站地震计运行的工作状态。

| Abstract: | Taking the seismometers used in some stations of Shanxi seismic network as the research object,the pulse calibration waveform data for a period of time are selected for calculation,and the characteristics of the working period and damping variation of the seismometers and the fault causes are analyzed.Combined with the practical work experience of operation and maintenance of seismic network,this paper puts forward the idea and method of detecting the working state of seismometer,and proves that the working state of seismometer can be reflected to a certain extent by regularly detecting the change of period and damping of seismometer. |
