摘　　要：机敏混凝土电阻率层析成像(ERT,electrical resistance tomography)是新近发展起来的一种可视性无损检测技术。为了对其深入研究,设计并实现了一个机敏混凝土ERT实验系统。系统的各功能模块都采用参数化设计技术,能够进行不同试件、不同电极数下ERT成像研究。实现了多种ERT成像算法,各算法参数和成像显示参数也可直接修改。介绍了该系统的主要功能及其实现方法,给出了部分ERT实验图。ERT（ electric resistance tomography） for CFRC structure is a new visual NDT method developed in recent years. To study deeply ERT, a ERT system is designed and accomplished. Each functional module of this system is designed with parametrization technology. The system is suitable for ERT experiment and investigation for different specimen with different number of electrodes. Many reconstruction methods are accomplished. Parameters of each reconstruction method and parameters for image showing can be modified directly. Main functions and its implementing methods are described. Several ERT images are also shown.
