地球内部扁率及其它物理参数的计算

Computation of the Earth's Internal Flattening and Some Other Physical Parameters

计算了地球内部任意半径处与密度分布相关的物理参数,如扁率、质量、重力、压强、平均主惯量、主惯量之差等,对应于初步参考地球模型(PREM)多项式及离散数字形式的密度模型给出了上述参数的多项式及离散数字模型。

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).
