【摘要】 上世纪90年代出现的电阻率层析成像技术是电法勘探的革命性进展，目前已在硬件和软件上取得重大发展．对数据采集系统，本文以 MIR/MIS 仪器为主从电极转换器、测量主机、控制软件、阵列电极和电缆系统几个方面全面地介绍了该技术的原理与设计，对主要的技术性能进行了讨论，对比和分析了不同设计思路的特点和利弊．简单介绍了国内外同类仪器的发展概况．更多还原

【Abstract】 Since the beginning of the 1990s,the resistivity tomography techinique has been made great developmentboth in the hardware and the software.Taking the MIR/MIS system for example,we interpret the designing principleof the data-acquiring system for resistivity tomography by detailed description of the measuring unit,multi-channelswitcher,electrodes-arranging,cables,and controlling software.The characteristics of different designing schemesare analyzed,and general situation of the development in the same kind of instruments is also introduced in this paper.更多还原
