英文摘要A new fast differentiation operator, "pseudospectral time-staggered difference operator", is proposed in this paper. The accuracy of this method is four time of the normal pseudospectral method. It is confirmed that the numerical dispersion of this method is less than that of normal pseudospectral method by comparing the calculation result of Marmousi model. The new operation is applied to simulate seismic wave propagation in 3-D heterogeneous medium, and the results show that the time-staggered difference operator for the pseudospectral method is valid for the seismic wave simulation in the complex heterogeneous medium.
