论文部分内容阅读
电磁振荡和电磁场是高中物理电磁学部分非常重要的内容,学生在学习振荡电路时普遍反映有困难,但将电磁场一节的内容调换到电磁振荡一节的前面讲解后,发现学生对电磁振荡现象的理解就要容易得多。但无论新教材还是旧教材,电磁振荡都是放在电磁场前面讲解的。那么在物理学发展史上电磁振荡电路和电磁场理论孰先孰后?它们之间又有怎样的本质联系?本文就这两个问题分别进行简单的探讨。
Electromagnetic oscillations and electromagnetic fields are some of the most important aspects of high school physical electromagnetism. Students generally have difficulty in learning oscillation circuits. However, after switching the contents of the electromagnetic field to the front of the electromagnetic oscillation section, students are found to have electromagnetic oscillations. The understanding is much easier. However, whether the new textbook or the old textbook, electromagnetic oscillations are placed in front of the electromagnetic field to explain. Then, in the history of physics, electromagnetic oscillation circuit and electromagnetic field theory have come into being first, and what kind of essential connection between them? This article will simply discuss these two issues.
