电容电阻率 (CR) 方法是传统直流 (DC) 电阻率方法的一种省时省力的替代方法。 CR 的线电极变体缺乏可用于直流电阻率方法的数据反演程序。应用直流反演程序，使用近似等效的四点偶极子-偶极子配置来确定 CR 测量的电阻率分布。我们使用基于所提出的直流近似的二维灵敏度比较的数据，优化了配置，以最大限度地减少将直流反演程序应用于 CR 的系统误差。最佳四点偶极-偶极几何结构的偶极长度为 80%。
The capacitive resistivity (CR) method is a time‐ and labor‐saving alternative to traditional direct current (DC) resistivity methods. The line electrode variant of CR suffers from the absence of data inversion programs as available for the DC resistivity method. Direct current inversion programs were applied to determine the resistivity distribution from CR measurements using an approximately equivalent four‐point dipole–dipole configuration. We optimized configurations to minimize the systematic error applying DC inversion programs to CR, using data based on the comparison of the two‐dimensional sensitivities of the proposed DC approximations. The optimal four‐point dipole–dipole geometry has a dipole length of 80%.
