测电源电动势和内阻实验中的系统误差问题,是物理教学研究的难点,也是热点,但是,在研究中也出现一些误区,以至于方法各有不同,甚至结论也有不同,本文用图像法进行研究,并指出研究中的一些误区.
It is a difficult point and a hot spot to study the system error in the electromotive force and the resistance experiment of the power supply. However, there are some misunderstandings in the research, so that the methods are different and even have different conclusions. In this paper, the image method Research, and pointed out some errors in the study.
