A combinational method of partial separation of variables and finite differences for computing the theoretical seismograms in stratified elastic media is studied. The basic formulae and equations are given, the boundary conditions at interior boundaries between layers are considered, and the numerical method and algorithm for computing the displacement fields of seismic waves in layered elastic media have been obtained. The results obtained in this paper show that the algorithm of this method is enough simple, the frequency range in which the theoretical seismograms are calculated can be broad, its precision is enough high, and the stability of this method is also good. For illustration of the method, some results of theoretical seismograms calculated for a given model of stratified lithosphere media are shown.

The shot function and wave impedance of homogeneously layered elastic media are inversed simultaneously via characteristic curve method in this paper. Numerical experiments show that the theoretical values of the shot function and wave impedance are matched well with the inversed ones. And the method is easy to implement and can resist noise to a certain degree.
