Abstract: The inverse problem of elliptic partial differential equation in the permeability field is discussed,whose permeability coefficient is nearly uniform.By using Radon transform in computerized tomography technology,the solution to this problem could be found,and some numerical examples are presented.

Key words: Radon transform, permeability dynamics, elliptic partial differential equation, inverse problem
