国家地震局分析中心研制成功DZB-I型地震仪自动标定器,可对地震仪进行脉冲标定和对放大器—记录笔系统的幅频特性作分段标定。 该仪器自动化程度高,在地震仪正常运转过程中,只要输入一个指令或启动按钮即可完成脉冲标定和从4秒—0.02秒25种不同周期的分段标定。该机设有
The DZB-I seismograph automatic calibrator has been successfully developed by the State Seismological Bureau Analysis Center. It can perform pulse calibration on the seismograph and segment the amplitude-frequency characteristics of the amplifier-stylus system. The instrument is highly automated and performs pulse calibration and segment calibration at 25 different cycles from 4 seconds to 0.02 seconds by entering an instruction or start button during normal seismograph operation. This machine is equipped
