标定地震仪器的常数是保证地震观测资料准确可靠的一项基础工作。在实际工作中,由于客观条件限制,往往不能及时标定,或因使用不同的仪器和方法,使得标定误差较大。在遥测传输地震台网中,由于记录中心与各子台相距遥远,常规的标定方法难以进行。为了改善标定工作的条件,最近研制了DZB-1型地震仪 The calibration of the constants of seismic instruments is a basic work to ensure the accurate and reliable seismic observation data. In practical work, due to the objective conditions, often can not be calibrated in time, or due to the use of different instruments and methods, making the calibration error larger. In the telemetry transmitting seismic network, since the recording center is far away from each sub-station, the conventional calibration method is difficult to carry out. In order to improve the calibration work conditions, recently developed a DZB-1 seismometer
