摘　　要：本文基于LabVIEW虚拟仪器开发平台,通过AD/DA接口板,开发实现了一套计算机控制的电化学测试系统.本系统通过计算机向测试系统发送外控极化信号,同时对极化电压和极化电流等实验数据进行自动采集、实时显示以及保存.在目前的工作中,系统实现了单程线性电势扫描伏安法和循环伏安法这两种最常用的电化学测试技术.利用开发的电化学测试系统对一些典型样品的极化曲线进行了测试,结果显示系统工作良好,数据准确.The work of this paper is to develop an electrochemical measurement system controlled by personal computer via AD/DA interface board based on LabVIEW platform. In the electrochemical measurement system, the computer generates the external control signal, acquires the polarization potential and the polarization current of the work electrode, displays their voltammetry curve and saves the data in the text file in the end. At present two conventional measurement methods of linear sweep voltammetry and cyclic voltammetry have been realized in this system. The polarization Curves of some ordinary materials had been measured by means of the constructed electrochemical measurement system. The measurement results had pointed out that this system works well and acquired data is exact.
