摘要
本文介绍了改制后ＤＤ－１型地震仪放大器、稳频器、稳压器的工作原理，简述了其主要技术指标，并给出了仪器的标定和试验结果．ＤＤ－１型短周期地震仪改制。是为了使仪器更好地适应地震预报与基础研究的观测需要而进行的。将改制后的仪器经室内测试标定和实际观测，并与沈阳地震基准台记录进行对比分析，证明改制后的ＤＤ－１型短周期地震仪主要技术指标与工作性能已达到规范的要求．
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.
