【摘要】 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。更多还原

【Abstract】 In this paper, three kinds of improvement are made against the disadvantages of Zhody inversion method. The inversion procedure of major digital model could stably converge if the depth transformation factor used to transform the space of electrode to depth is fixed; If a iterative coefficient is added to the formula used to adjust apparent resistivity, the calculated value will rapidly access to observation value, therefore the number of iteration is lowered. The noise will be effectively oppressed if filter factor is added to the data involved noise. The availability of Zhody inversion method used to two dimensional resistivity inversion is verified through digital simulation and field data. The simulation includes simple model and complex model, and both of them give us quite ideal application results.更多还原
