| 摘 要： | A seismometer data acquisition unit has been used in the Changping seismic station to record the output of a strainmeter.The output of a strainmeter was sampled at a rate of 100/sec by seismometer acquisition from the original rate of 1 per minute.Plenty of high frequency sampled data was recorded.The minute value curve calculated from the seismometer acquisition are consistent with that of the original data sampled by the strain acquisition system.More complete waveforms were recorded with a higher sampling rate,and seismic phase parameters calculated by using higher sampling rate strain seismic waves are also in consistency with the results of its predecessors.Spectra of the strain seismic waves are compared with that of seismic waves recorded by a seismometer in the Shisanling seismic station,and their trends are almost the same.Besides,some lower frequency components still exist in strain seismic waves.

| Abstract: | A seismometer data acquisition unit has been used in the Changping seismic station to record the output of a strainmeter. The output of a strainmeter was sampled at a rate of 100/sec by seismometer acquisition from the original rate of 1 per minute. Plenty of high frequency sampled data was recorded. The minute value curve calculated from the seismometer acquisition are consistent with that of the original data sampled by the strain acquisition system. More complete waveforms were recorded with a higher sampling rate, and seismic phase parameters calculated by using higher sampling rate strain seismic waves are also in consistency with the results of its predecessors. Spectra of the strain seismic waves are compared with that of seismic waves recorded by a seismometer in the Shisanling seismic station, and their trends are almost the same. Besides, some lower frequency components stiil exist in strain seismic waves. |
