Earth tide force is divided into two component forces, and their continuity characteristics are discussed in ecliptic coordinate system. The global distributions of the components are derived based on the waist leveldistribution characteristics of their amplitudes. The attributes of the crossing points of the global distribution curves are also analyzed. The expression method of the equivalent curves of ocean tide amplitude is studied in rectangular coordinate system. The variation of the position of maxinum earth tide amplitude in earth revolution,and the variations of the position and time of it in earth rotation are stated. It is concluded that the tidal component forces cause the symmetry of tidal wave amplitude;the equivalent curves of the tidal wave amplitude are annular;the maxinum amplitude of ocean tide depends on the quality of the seawater in the sea area;the continuity characteristics of atomsphere tide and mantle tide amplitudes are similar to those of ocean tide amplitude.
