本文讨论了近几年提出的、1979年在日本开始采用的频谱激发极化法或多频激发极化法(或复电阻率法)的特点.该方法的基本优点是能减弱使野外资料解释复杂化的感应效应的影响.文中描述了工作方法和测量装置的框图.与传统的激发极化法一样,在此也利用了偶极装置.电流借助于转换装置通过事先布置好的9个电极中的2个(图1)供入地下.接收线路由三个电极组成,并且其中的中间电极是相对P_1和P_2的基准电极.为了加强抗干扰能力(提高信噪比),在仪器中有微型计算
This article discusses the characteristics of spectral excitation or multi-frequency excitation polarizations (or complex resistivities) proposed in recent years that were introduced in Japan in 1979. The basic advantage of this approach is its ability to mitigate the effects of field data interpretation Complexity of the sensing effect of the article described in the working method and the measuring device block diagram, as with the traditional excitation polarization method, where also used dipole device current by means of the conversion device through the pre-arranged nine electrodes (Figure 1) into the ground.The receiving line consists of three electrodes, and the middle electrode is the relative P_1 and P_2 of the reference electrode.In order to enhance the anti-interference ability (to improve the signal to noise ratio) in the instrument Micro-computing
