地球主惯性矩

Earth's Principal Moments of Inertia

地球主惯性矩属于大地测量学和天文学的基本地球参数。研究地球主惯性矩及有关问题。第一节研究主惯性矩和地球扁率的计算公式;第二节研究主惯性轴坐标系中2阶位系数的计算;第三节研究地球主惯性轴方向的确定方法,第四节给出地球主惯性矩、主惯性轴方向和地球扁率的数值结果。

The Earth's principal moments of inertia are the geodetic and astronomical fundamental Earth parameters. The paper is devoted to the Earth's principal moments of inertia and the related issues. Section 1 formulates the Earth's principal moments of inertia and the Earth's flattening; Section 2 deals with the computation of the second-degree harmonic coefficients in the principal axes coordinate system; Section 3 studies the directions of the Earth's principal axes of inertia, and Section 4 presents the numerical values of the Earth's principal moments of inertia, and of the orientations of the Earth's principal axes of inertia, and of the Earth's flattening.
