| 英文摘要 | The scalar equations of infinitesimal elastic gravitational motion for a rotating, slightly elliptical Earth are always used to study the Earth's nutation and tides theoretically, while the determination of the integration of the equations depends, to a certain extent, on the choice of a set of appropriate boundary conditions. In this paper, a continuity quantity related to the displacement is first transformed from the elliptical reference boundary to the corresponding effective spherical domain, and then converted from a vector (or tensor) form to a scalar form by generalized surface spherical harmonics expansion. All the related components, including the displacement vector field (or the stress tensor field), are then decomposed into the poloidal and toroidal field using the symmetry restrictions on the normal mode eigenfunctions. After truncation, the boundary conditions are finally derived, in a scalar ordinary differential form. The process of the derivation is second order in ellipticity and in full detail. Moreover, the other boundary conditions are also presented as second order in ellipticity at the end of this paper. |
