这是一节实验操作课,实验的内容大家都很熟悉:《用伏安法测量电阻》(如图1)..由于器材的限制,我们无法使每个同学都获得单独操作的机会,只能以3～4个人为一个小组分组进行实验.
This is an experimental operation lesson. The content of the experiment is very familiar to everyone: “Measurement of resistance with voltammetry” (Figure 1). Due to equipment limitations, we cannot make every student have the opportunity to operate alone, only 3. Experiment with 3 to 4 individuals grouped into groups.
