在物理教学过程中,常常遇到关于临界状态的问题,临界状态对学生来说是一个难点,遇到这种问题总感觉到无从下手,难以寻找解决问题的关键所在.因此,我们来探讨一下关于临界问题在高中物理教学中的应用很有必要. 什么是临界现象?所谓的临界现象是指:既可理解成“恰好出现”也可以理解为“恰好不出现”的物理现象.当一种状态变为另一种状态时,往往会伴随着一个转折点,而这个转折点,就是我们所要找的临界状态.关于它的主要应用,总结如下:
In the process of physics teaching, there is often a question about the critical state. The critical state is a difficult point for the students. When confronted with this kind of problem, it is always difficult to find the key to solve the problem. Therefore, we have to discuss The application of the critical question in high school physics teaching is necessary. What is the critical phenomenon? The so-called critical phenomenon refers to: it can be understood as “just happens” and can also be understood as “just happens” physical phenomenon. When a state changes to another state, it is often accompanied by a turning point, and this turning point is the critical state we are looking for. The main application of it is summarized as follows:
