| Abstract: | Working principle of the amplifire,the frequency stabilizer and the stabilizator of seismograph DD-1 remade has been introduced in this paper,their main technological index and results to calibrate and to test the instrument have been also given. Having observed in practice and compared with the record of Shenyang seismic station, it is proved that main technologica index and working function of the short-period seismograph DD-1 remade have reached requirement of the standard. |
