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.
由该模型的分析结果表明，其阻尼值比之按两参数模型以及按弹性半空间体的理论模型求得的值要小得多。

Therefore, the travelling wave effect should be considered for the selection of the parameter values of semi-active control system in order to get the designing control effect.
