摘　　要：介绍了数字地震仪系统传递函数的特征和测定方法,给出了地震仪标定软件的使用方法和计算步骤。结合实际波形数据处理过程,着重对标定计算中参数的设置,以及需要注意的问题进行了讨论和分析。这对于正确快速地获取地震仪的传递函数具有重要的现实意义,有利于国家数字地震台站和区域地震台站地震观测系统的定期标定工作,同时也将促进数字化地震观测资料的应用研究。The characteristics of transferring function of digital seismographs and their calibration method are introduced firstly, and then the procedure of calibration waveform process using the software released by the Gangzhen Corporation, Institute of Earthquake Science for calibrating seismograph is described in detail. Parameter setting and some questions requiring special attention are emphatically discussed and analyzed. These are significant for quickly acquiring transferring function of digital seismograph, beneficial to the routine calibration of state digital seismic stations and regional seismic stations at regular interval, and can also promote the application of digital seismic seismograms.
