Having leaded the semi-parameter model into the geodetic inversion model, the effect of surveying data systemic error is eliminated or weakened on the geodesy inversion model.

It is shown that the damping value established from three parameter model is smaller than that of two parameter model or elastic semi-infinite body theory.

The steady state term is the steady flow stress model of metal materials in the semi-hot forming process, and it is a model related to the Z parameter;
