贵刊2010年第5期刊登了李维兵老师的《伏安法测电阻实验中系统误差的消除》一文,笔者读后总感觉有些地方言犹未尽,尤其是某些关键之处,不吐不快,特撰文说明.伏安法测电阻实验共有两种接法,如图1、2所示.众所周知,在图1中,要消除系统误差,需去除电 Published in the fifth issue of 2010 Li Weibing teacher “Voltammetry resistance measurement experiment to eliminate systematic errors,” one article, the author always feel some words to say unresolved, especially some of the key points, do not spit not fast , Special author explained voltammetry resistance test there are two ways to connect, as shown in Figure 1, 2. As we all know, in Figure 1, to eliminate systematic errors, the need to remove electricity
