A STUDY ON THE INVERSION OF THE VELOCITY STRUCTUE OF THE CRUST AND UPPER MANTLE BY THE USE OF CONVERTED WAVES AND SECONDARY WAVES of THE NATURAL EARTHQUAKE

An inversion of velocity structure of crust and upper mantle by using converted PS wave and multiwave PPP etc, is reported in this paper. A "step by step and layer by layer" methed is introduced to linearize the inversion Problem. Error analysis and some practical application are also given, some problems and further development are pointed out.
