摘要：

We consider the problem of determining the spatially varying conductivity of a two-dimensional body from electrical measurements made on the boundary. A method for solving the linearized problem was suggested by Calderon. His method was used previously to solve the linearized problem in the case of two homogeneous concentric conducting discs with different conductivities. This paper presents the exact solution to the linearized problem for the case of three concentric discs. As in the case of two discs, the locations of the discontinuities are recovered exactly.
