摘　　要：本文介绍的区域综合地震数据库系统,通过采取一定的技术措施,不仅具有一般应用软件模块化的程序结构、通用性及可移植性强、设计简洁明快、用户界面友好以及容错纠错功能强等特点,而且研制出了记忆性(智能化)的录入模块,用于大量地震资料的录入,可成倍提高工作效率;在按台项建立子库的基础上,采用等分算法进一步实现了快速检索功能,该功能不论是对于等时间间隔序列还是对于不等时间间隔序列的观测资料,都能提高查询速度数倍。这些方法不仅适用于地震数据管理,同样适用于其它行业类似的大量的资料管理和查询。The regional comprehensive seismic data base system introduced in this paper, by taking a certain technical measures, not only has the modular program structure of an ordinary applied software, has an all—purpose property and a strong portability, has a simple design, a friendly user's medium and strong fault freedom and error correcting property, but also has a memory (intelligent) input modulor which can be used for a large amount of input of seismic data and by which the working efficiency has doubled; based on setting up sub data baese in terms of stations and items, using isodivision algorithm further realized fast retrieve function, which can raise the inquiry speed several folds either for the data of equal time interval sequence or unequal time interval sequence. These methods not only can he used to seismic data mana gement but also can be used to the data management and inquiry of a large amount of similar data in other areas.
