摘要: 从简化的地月系统力学模型出发,严格推导出地表物体动力学方程在转动坐标系下的表示形式,通过对称性的分析,得到引潮力,从而有助于加深对引潮力和潮汐成因的理解.

Abstract:

 Starting from the simplified mechanical model of the earth-moon system,the dynamic

equations of the surface object in different coordinate systems are derived strictly,and through

the analysis of symmetry,the tid- al force is obtained,which is helpful to understanding of the

tidal force and the cause of tide.

Key words: tide, moon, tidal force, symmetry
