针对佐迪反演方法在二维拟断面应用中的缺陷进行了三个方面的改进：固定佐迪反演方法中用于转换电极距和深度关系的深度转换因子，可使绝大多数数字模型的反演过程稳定收敛；在调整视电阻率的公式中加入一个迭代系数，可使计算值快速趋向于观测值，减少了迭代次数；对于含有噪声的数据，加入滤波因子可以在一定程度上抑制噪声。通过数字模拟和野外实测数据对改进后的佐迪反演方法在二维电阻率反演应用中的可行性进行了验证。模拟研究包含了简单模型，也包含一些复合模型，二者均取得较理想的应用效果。
The defects of Zodiac inversion in the application of 2D quasi-section are improved in three aspects: the depth conversion factor used to transform the relationship between electrode depth and depth in the fixed Zodiac inversion method can make most digital models The inversion process is stable and convergent. By adding an iterative coefficient to the equation of apparent resistivity, the calculated value rapidly tends to the observed value and reduces the number of iterations. For the data containing noises, adding the filter factor can restrain to a certain extent noise. The feasibility of the improved Zodiac inversion method in the application of 2D resistivity inversion has been verified by numerical simulation and field measurements. Simulation study includes a simple model, but also contains some composite models, both of which have achieved better application results.
