摘　　要：本文介绍便携式微机化电位溶出分析仪的硬件和软件结构。仪器采用单片机为核心组成控制及测量系统,简化接口电路,改由传统的人工模拟调节方式为计算机数字调节方式。通过电子开关电路进行检测过程中电路的高速切换,增设多扫描技术,强化检测功能,实现室外现场元素的自动分析。实现了仪器与PC机联机通讯,进行分析曲线的静态和动态显示,以及复杂的数据和结果处理。The hardware and software structures of a portable cornputerized potentiometric stripping analyzer are described. The central part of the control and measurement system is a single chip computer. The interface circuit is simplified and manual analog regulation is replaced by computer-controlled digital regulation. The high speed switching in the process of measurement is performed by electronic switch circuit. Multiscan technique is provided to increase analysis function so that field in situ automatic element analysis can be performed. The communication between a PC and the analyzer is made possible for the static and dynamic cjisplay of analysis curves.
