%X The spectral element method based on a weak elastic mechanical equation extends the equation in the form of spectral with the idea of the finite element method.So it combines the advantages of the finite element method with the ones of the pseudospectral method.That is,the geometrical flexibility of the former and the accuracy of the latter.Here,we do prestack reverse-time migration on two different models with anisotropic media.The examples prove that the results of migration are well in accordance with the models.
