等效替代法是物理方法中应用广泛的重要方法,是科学研究中常用的一种思维方法.在效果等同的前提下,把实际的、复杂的物理过程变成理想的简单的等效过程来处理,可使计算大为简化,又可加深对物理概念、规律的理解.学生学到的等效方法是从具体的实例中体验来的,他们对于等效法的认识是割裂的、分散的,往往是一种错误的观念,认为等效的两个物理现象应该具有相同的本质.这种认识上的错误妨碍他们对等效法的普遍性认识.实际上,等效法是不论性质的,这种思想方法准则
Equivalent substitution method is an important method widely used in physical methods. It is a commonly used thinking method in scientific research. Under the premise of equal effect, the actual and complex physical process is turned into an ideal simple equivalent process. Processing can greatly simplify calculations and deepen the understanding of the concepts and laws of physics. The equivalent methods that students learn are experienced from specific examples. Their understanding of equivalent methods is fragmented and decentralized. It is often a misconception that the two physical phenomena of equivalence should have the same essence. This kind of cognitive error hinders their understanding of the universality of the equivalent method. In fact, the equivalent method is of any nature. Thought method guidelines
