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。
The physical parameters related to the density distribution at any radius inside the Earth are calculated, such as the flattening rate, mass, gravity, pressure, average principal inertia, and the difference of the principal inertia. Corresponding to the PREM polynomials and discrete digital forms The density model gives the polynomial and discrete numerical models for the above parameters.
