中文摘要： 模拟地震监测波形记录是研究和预报地震的基础数据，我国三十多年的模拟地震监测波形记录涵盖了大陆地区破坏性地震极其活跃的时期，是地震监测预报的一段重要历史。因为破坏性地震并不是经常发生，对于纸介的模拟地震监测波形记录，保存、利用十分困难，更无法利用现代计算机技术和数据挖掘方法对其进行深入有效的信息挖掘。精准矢量化模拟地震监测波形记录有助于完整、真实保存已有的模拟地震监测数据；有利于开展地球物理背景场分析研究，充分挖掘地震前兆信息；为地球科学研究提供可靠、完整的基础数据，对推进地震科技发展具有重要的现实意义和深远的历史意义。本项工作的主要内容包括：研究模拟地震监测波形记录矢量化的关键算法；基于大数据平台设计模拟地震监测波形记录的存储、分发方案；开发一套高精度的模拟地震监测波形记录自动矢量化与存储、分发软件系统。

英文摘要： Analog seismic records are very important information for earthquake monitoring and prediction. Analog seismic recording technology had been used more than thirty years in china when the destructive earthquakes is very active in the mainland of china, and that has always been the important history of earthquake monitoring and prediction. As is known, devastating earthquake does not often occur, but whose analog seismic records is not convenient to store and read, and cannot still been processed such as seismic data mining and extraction easily and quickly by computer without further vectorizing. By vectorizing analog seismograms precisely and speedily, which is conducive to save historical analog seismograms and helps analyze geophysical background and mining earthquake precursor information, and all of these has important actual significance and deep historical significance for the development of seismological science and technology. Our work mainly includes: researches on key algorithms in analogue seismograms vectorization, designs storage and distribution scheme for analog seismogram based on big data platform, develops a set of automatic vectorization with high precision and storage and distribution software system for analog seismograms.
