Abstract: In this paper,the flattening,mass,gravity,pressure,mean principal mo-mentum of inertia,difference of principal momentum of inertia at any radius in the interior of the Earth are computed.Their polynomial and discrete digital representa-tions are given in aecordeuce with that of the Preliminary Reference Earth Model (PREM).
