一、前言众所周知,微型计算机是70年代重大科技成就之一,是一种理想的自动化技术手段,它正在迅速发展并广泛应用于各个技术领域。微型计算机的一个重要应用是数据采集和过程控制,如何将其用于腐蚀研究是一个很有意义的课题。电偶腐蚀实验是腐蚀研究中的一个重要手段,在科研与生产中需要测试电偶电位Eg、电偶电流g随时间变化的规律。过去,这种实验均采用电偶腐蚀计进行,劳动强度大,目测读数,测试精度也不理想。
First, the preamble As we all know, micro-computer is one of 70 major scientific and technological achievements, is an ideal means of automation technology, it is rapidly developing and widely used in various technical fields. An important application of microcomputers is data acquisition and process control. How to use them for corrosion research is a very significant issue. Galvanic corrosion test is an important means of corrosion research, in the research and production needs to test the galvanic potential Eg, galvanic current g with the law of time. In the past, these experiments are used galvanic corrosion meter, labor-intensive, visual readings, test accuracy is not satisfactory.
