Then, the orbit of the Moon about the earth could be a consequence of the gravitiational force, because the acceleration due to gravity could change the velocity of the Moon in just such a way that it followed an orbit around the earth.

如此说来，月球的轨道应该是地球引力的结果。因为引力产生的加速度会改变月球的速度，使它按一个绕地轨道运转。

The non-relativistic energies and wave functions were determined by Rayleigh-Ritz method. The relativistic effects, including the correction to kinetic energy, the electron-electron contact term, and the orbit-orbit interaction, Darwin term, and mass-polarization effect on the energies were calculated by using first-order perturbation theory. In order to obtain a more accurate result for the larger Z system, the quantum-electrodynamics correction should be included. This correction to energy can be evaluated for the valence electron by using a hydrogenic formula with an effective nuclear charge, Z. The ionization potential, the excitation energies and the fine structure split-tings for a lithium-like ion with higher nuclear charge (Z=26) were calculated.
