It has been shown that application of central differences describes wave processes in the models considered the best. Additional physical and mathematical conditions for transition from finite difference model to continuous one have been determined. New relations between discrete sampling interval and physical properties of the medium have been obtained enabling application of the method in seismological problems. Conditions for correct application of finite difference models have been derived.5635 Product Description popup.authors popup.nrat_date 2020-04-02 Close
