等效思想在高中物理新课程教学中有重要应用,按等效形式的不同,可将其分为模型等效替代、过程等效替代、作用等效替代、本质等效替代四种。每种等效形式都有其独特的等效条件、巧妙思想和应用魅力。 Equivalent thinking has an important application in the teaching of new physics in senior high school. According to the difference of equivalent forms, it can be divided into equivalent substitution of the model, equivalent substitution of the process, equivalent substitution of the function, and essentially equivalent substitution of the four. Each equivalent form has its own unique equivalent conditions, clever ideas and applied charisma.
