    • Abstract
  • According to the theory proposed by Wahr in 1981,detailed formulas for calculation of the gravity,tilt and strain tides have been derived for a rotating elliptical,elastic earth model and on the basis of these formulas a computer program has been compiled. In order to reveal the influences of the rotation and ellipticity of the Earth on the gravity,tilt and strain tides,these values have been calculated for an elliptical,rotating,elastic earth model (1066 A) and G-B earth model for longitude 120°E and different latitudes. The calculated results show that the maximum influences of rotation and ellipticity on gravity,tilt and strain tides are resplcti-vely: 1.4×10-8 m/s2
    , 0.2 ms and 0.5×10-9.
