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… 相似文献
