【Abstract】 The seismic amplifier of ARA type is a integrated amplifier which can be shifted automatically. Its performance score shows that the character of every kind of seismic amplifier which composed by the parts of ARA has increased greatly. This paper is one of the articles which describes the concrete application of ARA seismic amplifier on every kind of seismic recorder. It also expounds that every technical problems should be solved for the application of ARA on the seismfc recorder ( DD- 1 )更多还原
