摘　　要：恒电位仪是在合金相电解提取中精确控制阳极溶解过程的重要仪器。论文开发了一种用单片机控制的恒电位仪样机。详细介绍了恒电位仪的原理、电位补偿设计和硬件软件滤波方法,并给出了软件设计框图和试验实例。样机在试验室内的可靠运行表明其设计是合理的。The potentiostat is one of the principal instruments used to control an anodic dissolution process accurately in electrochemical experiments. The potentiostat prototype is developed based on a single-chip microcontroller （SCM）. The paper presents the design prineiple, iRu compensation, and digital filter method, and then gives out the design of software block diagram and some experimental instances. Its reliable performance in a lab justifies the effectiveness of the developed instrument.
