EXPERIMENTAL STUDY OF TECHNICAL TRANSFORMAION OF SHORT PERIOD SMOKED PAPER RECORDING SEISMOGRPHS
To counter the problem existing in smoked paper recording seismographs, only by changing the amplifier, power supply and recording part, using the existing seismic geophne and large drum recorder, and using little fund, the short period smoked paper recording seismographs can be transfored to a new type DYJ-1 short period ink-writing seismographs.
