在迎来中国数字地震台网运行１０周年之际，９个台站设备的二期技术改造工作业已胜利完成。目前，这些台站配置了先进的计算机系统——ＳＵＮ公司的ＳＰＡＲＣ系列台式工作站。其上安装了相应的地震分析软件，使得应用高质量的数字化数据进行地震分析成为可能，并弥补了模拟记录的许多不足。这无疑为台站工作人员及其它科研人员在台站现场进行地震分析工作，提供了十分便利的条件。但波形数据在ＳＵＮ工作站上的驻留是一个动态的过程，一般只能保存３～４天，这给研究人员进行从容细致的应用分析造成了巨大的困难。本文着重介绍对这一问题的研究和解决方法。
On the occasion of the 10th anniversary of the operation of China's digital seismograph network, the second phase of technological transformation of 9 stations and equipment has been successfully completed. Currently, these stations are equipped with state-of-the-art computer systems - Sun's SPARC series of desktop workstations. With the corresponding seismic analysis software installed on it, it is possible to apply high-quality digital data for seismic analysis and make up for many shortcomings of analog recording. This will undoubtedly provide very convenient conditions for station staff and other researchers to carry out seismic analysis work at the station site. However, the residency of waveform data on the SUN workstation is a dynamic process and can only be stored for 3 to 4 days in general. This poses great difficulties for the researchers to carry out a calm and meticulous application analysis. This article focuses on the research and solution to this problem.
