摘　　要：研制了一套便携式电化学数据检测和处理系统,系统有便携式计算机、计算机接口、测量探头、恒电位仪和用VisualBasic计算机语言编制的基于MicrosoftWindows95或Windows98的可视化数据采集和处理计算机软件组成。系统中的等电位图和电脉冲暂态响应两种技术,能方便、可靠地评估钢筋混凝土建筑物中钢筋的腐蚀区域,模拟电路及实际混凝土构件上的应用结果表明,该系统测量分析结果可靠。An electrochemical measuring and analyzing system for evaluating rebar corrosion in concrete was developed. The system consists of portable computer, computer interface, measuring probe, potentiostatic instrument and data-collecting and analyzing computer software programmed in Visual Basic 6.0 and suited to Microsoft Windows 95 or Windows 98, it includes two techniques of iso-potential map and electric-pulse signal transient response. Applications in simulating circuits and reinforcement concrete member show that results obtained by the system is reliable, and can measuring and evaluating rebar corrosion in concrete buildings conveniently and reliably.
