| 摘 要： | 以浙江省测震台网部分台站地震计为研究对象,选取一定时间窗口对阶跃标定波形进行计算,得出地震计在该时段内的周期和阻尼变化情况。结合台网台站运行维护工作,经过统计分析,表明利用此方法能够在一定程度上反映出台站地震计运行的异常状态。

| Abstract: | Taking some seismometers installed at stations of Zhejiang Seismic Network as the cases ,the step stimulus calibration waveforms within a certain time window are calculated to get the variations of the period and damping of the seismometers .The sta-tistical analysis indicates that the method used in the paper can detect the abnormal state of the seismometer at the station in some de-g ree . |
