【摘要】 电阻率勘探法一直是水文、工程、环境物探中所采用的重要方法之一。然而常规电阻率法由于其本身工作方式限制，致使其所获取的信息数量较少，更难于从多种电极排列的组合上去研究地电断面结构。高密度电阻率法正是为弥补上述不足而产生的。本文详细介绍了高密度电阻率测试系统，特别是其关健部件程控式多路转换器的原理及设计。更多还原

【Abstract】 The resistivity prospecting is one of the important method used in geophysical prospect-ing of hydrology,engineering and environment.Because of the limitations of its working way,the less information is collected.High-density resistivity prospecting can solve this problem.The paper introduces theory and design of high density resistivity prospecting testing sys-tem,especially the programming multiplexor in its key components.更多还原
