由于数字地震记录仪具有记录频带宽，分辨率高，动态范围大以及易于用计算机处理等优点，所以数字地震台网产出的数字地震资料成为地震活动性、震源机制、地球内部研究、地震监测及预报等的最基本数据源。中国数字地震台网（ＣＤＳＮ）是这样一种高度智能化的地震观测系统，它为地震研究提供高质量的数字地震资料。本文从实用的角度，介绍如何使用ＣＤＳＮ数字化地震资料、数据文件格式、转换程序及其数字地震记录处理和分析软件。
Due to the advantages of high recording frequency bandwidth, high resolution, large dynamic range and easy processing by computer, digital seismic data generated by digital seismograph network has become one of the key technologies of seismic activity, focal mechanism, intra-Earth research, seismic monitoring And forecast the most basic data source. China Digital Seismograph Network (CDSN) is such a highly intelligent seismic observation system that provides high-quality digital seismic data for seismic research. This paper presents a practical perspective on how to use the CDSN digital seismic data, data file formats, conversion programs and their digital seismograph processing and analysis software.
