The maximum difference of geoidundulation between the model and EGM96(to 70 degrees) is 2.
该模型与EGM96相比（70阶次），大地水准面起伏差异最大为2。

The altimetry geoidundulation is mainly conducted by convergence between two or three plates, and its components at short wavelength characterize tectonics within basins.
测高大地水准面反映了研究区板块相互作用的特点，其高频成分可以刻画各海盆的构造特征。

The geoidundulation diagrams in different degrees are mapped by WDM94 model. The relationship between the geoidundulation and the lateral inhomogeneity of regional tectonics is discussed.
