| 摘 要： | IntroductionSeismograms contain seismic wave data recorded by instruments. They are the main information source for seismological studies. Now we are developing seismological stations with digital records, which can offer seismic wave data with better quality than before. But the paper analog seismograms accumulated in the past decades still have great room for application. They are important original data for studying earthquakes. Lots of valuable information are contained in them. Due to a… |

| Abstract: | This paper introduces a (Seismogram Digitization and Database Management System( (SDDMS), which is developed using Delphi3, and present the key technique of automatically extracting wave data from paper seismograms. The system has various functions, such as paper seismogram digitization, database management and data analysis, etc. With this system it is possible to analyze historical paper seismograms using modern computers. Application of this system will be of help to the progress in earthquake prediction and seismological researches. |
