| Abstract: | The authors proposed a method for obtaining high\|quality acceleration records from velocity type records of the digital seismometry network,and take an earthquake record as an example for analysis and processing.This earthquake was simultaneously recorded by velocity seismograph CTS1-EDAS24 and acceleration seismograph EST-Q4128 installed in Jixian,Tianjin. The calculation steps and the processing method has been discussed in detail.From the analysis and the comparison of the obtained results,it is concluded that the proposed method is effective and it broads the application of the digital seismometry network. |
