所谓化归思想,是转化和归结的简称.就是在研究和解决比较复杂的物理问题时,采用某种思想.如:借助已知条件、物理图象、物理公式或物体的某种运动规律等,将一些比较复杂的问题通过变换或转化,将抽象的转变为具体的、复杂的转变为简单的、生疏的转变为熟悉的、未知的转变为已知的……从而达到迅速、合理的解决问题.利用化归思想解决比较复杂的机械波问题,一般可以先把问题化归为机械波的三个基本模型问题,而后再利用三个基本 The so-called return to thought, is the abbreviation of conversion and sum up is the study and solve complex physical problems, the use of certain ideas, such as: with known conditions, physical images, physical equations or some kind of law of movement of objects , Transforming some complicated questions into concrete and complex ones by transformation or transformation, transforming simple and unfamiliar ones into familiar and unknown ones ... so as to achieve a prompt and reasonable solution Problem.With the return to the thought to solve the more complex mechanical wave problem, the problem can generally be first classified as mechanical wave three basic model problems, and then use three basic
