在图形化虚拟仪器编程语言LabVIEW平台上开发了虚拟128电化学接口(EI)软件,实现了对英国Solartran公司生产的1286EI的通讯，可以在微机上通过RS232串口或GPIB并口控制1286EI进行各种腐蚀电化学实验；点击虚拟前面板上的按钮可以直接完成恒电位、恒电流和电位台阶等腐蚀电化学测试.
The virtual instruments (VI) technology and its characters were discussed in this paper.We present a software developed on graphical programming language LabVIEW that can communicate with the 1286 electrochemical interface (EI) which is made by Solartran and allow users control the equipment efficiently.By means of serial port or GPIB port,there by the software can control the instrument.The VI is designed using the LabVIEW and is capable of performing on-line measurement functions, including data acquisition,display,and analyses,as well as data archiving.Taking advantage of some other software,the corrosion electrochemical parameters can be calculated easily. KEY WORDS：corrosion electrochemistry；virtual instrument；GPIB；on-line measurement
