摘要
文中从电极排列、反演处理方法、仪器等几个方面 ,介绍了高密度电法的发展 ,说明了所有电极排列方式是从对称四极、单极偶极和单极单极发展而来。在反演方法软件方面 ,介绍了基于圆滑约束最小二乘法及计算机反演快速计算程序。同时 ,提出供电时间、极化补偿和电极转换开关是高密度电法仪器发展的关键技术。文中列举了高密度电法在多个领域的应用简况 ,最后提出了高密度电法在今后发展的趋势为高密度激发极化法、三维高密度电阻率法。
The development of 2D resistivity imaging surveys is introduced including electrodes array, data inversion and instrument. The switch time of current electrodes, SP compensating and switches of multi electrodes are the special technology in the instrument of multi electrodes system. Some examples of application of 2D resistivity imaging surveys are represented over many domains. The developing tendencies of 2D resistivity imaging surveys are also discussed.
