论文部分内容阅读
人民教育出版社出版的2003年秋季使用的初三《物理》教材P154图11-12出示了奥斯特实验(如图1),这是一个典型的著名的演示实验,笔者对这个知识点颇有想法和建议: 一方面,课本中的图示不妥当。因为这本物理教科书第四章第五节中规定了不允许把电源的两极直接连在一起,并且出示了一个明显的如图2所示的标记。而图1所示的奥斯特实验中两次出示了电源短路的现象,这岂不是有悖于第四章的规定吗?这岂不是教材知
The 11th “Physics” textbook P154 used by the People’s Education Press in the fall of 2003 shows the Auster experiment (Figure 1). This is a typical well-known demonstration experiment. The author is quite familiar with this knowledge. There are ideas and suggestions: On the one hand, the illustrations in the textbooks are not appropriate. This is because the fourth chapter of this physics textbook stipulates in Section 5 that it is not allowed to connect the two poles of the power supply directly together, and shows an obvious mark as shown in Figure 2. However, the Oster experiment shown in Figure 1 shows the phenomenon of power short-circuiting twice. Isn’t it contrary to the provisions in Chapter 4?
