本文介绍了如何用磁矢量成像方法获得磁矢量的分布。
The paper introduces how to get magnetization vector distribution by magnetization vector tomography and reports some modeling results. We divide 2D-research domain into a series of rectangular boxes and derive the Jacobian matrix element Aij that represents the relation between the magnetization of the ith box and thejth observed data on or above surface. Then we form the magnetization vector tomography equations and use Gauss-Sadell iteration method to solve such equations with proper depth weight coefficients for each equation and zero values for initial magnetization. Model tests are employed. The modeling result show that the inverse magnetization values are very close to model's ones respectively except for few boxes. In the same time, the successful test demonstrates that there is a great potentiality to determine magnetization vector distribution in detail with this method in practice, and the further research for the method will bring outstanding progress.
