【Abstract】 The HD- JSⅡeddy geophone is a pattern of seismic geophone based on the operational principle of bow wave and acceler- ation, which is suit for the exploration of all regions. This paper proposes an arithmetic to identify the characteristic parameters of eddy geophone on basis of the vibration mechanics theory of the configuration of the geophone and its working principles. The arith- metic can identify the parameters of inherent frequency, damp, delicacy and so on. It also offers a theoretical base to the eddy geo- phone testing instrument.更多还原
