前言“地震数据文件管理组”主要是为了管理地震年报和地震月报的数据。地震数据格式以子记录为单位被建立在五吋软磁盘內。一个月的地震数据就构成一个“地震数据文件”。解调数据文件可以生产地震月报的排版格式,可供影印制版印刷。编制印刷国际地震中心ISC所规定的震中参数格式数据,震相参数格式数据,作为同ISC交换地震资料使用。与此同 Foreword “Seismic Data File Management Group” is mainly for the management of earthquake annual reports and earthquake data. Seismic data formats are built into five-inch floppy disks in sub-records. One month’s seismic data forms a “seismic data file.” Demodulating data files can produce a format for the monthly earthquake report for photocopying. Prepare epicenter parameter format data and seismic phase parameter format data as stipulated by the International Seismological Center ISC for use as seismic data exchanged with ISC. Same with
