| Abstract: | We have transformed the seismograph of smoked paper
recording made in the sixties. The smoked paper recording and pendulum of DD-1 are retained in this transformation. The linear amplifier is replaced by integral amplifier of ARA and integral recording pen by linear pen.Ele-ctric alarm and automatic cutting power supply of alternating and direct are allocated to compose the new system of seismic observating instrument. After applicated in the seismic stations of Guangdong Province, this instrument moves in good order and good results are achieved. |
