摘要
用有限元法作电阻率层析成象的核心问题是Jacobi矩阵的求取和反演成象算法的研究．本文主要论述了这两方面的最新进展，即求取Jacobi矩阵的格林函数法，用于反演成象计算的平滑度约束反演，文中通过理论模型的成象计算，比较了两种反演算法的成象效果．
<Asbtract>To calculate Jacobi matrix and to inverse image algorithm are the main aspectsofresistivity tomography. In this paper, the latest developments about calculating Jacobimatrix and inversion algorithm are introduced. Finally, We compare the imagie results oftwokinds of imaging algorithms by means of calculating a theory model.
