主　　题：damped wave equation impedance identification seismic exploration Cauchy Problem principle of Pulse Variation. 

摘      要：Based on the damped wave equation,the damped wave equation for seismic exploration is given for the study on evaluation problem of stratum acoustic impedance by the seismic data *** applying Cauchy Problem instead of mixed problem in the process Of identifying acoustic impedance,we for give a fast identification algorithm of recurtive layer by *** order to avoid the accumulation of errors while identifying,the method of removing errors layer by layer is *** using the principle of Pulse Variation and even under the circumstance of big noise,we can identify the structure of stratum clearly.
