模型分为实物模型和过程模型.从其应用角度谈,无非是相似和等效,而在解决物理问题的过程中,恰当地运用等效模型思想方法,则可将一些复杂问题的解题思路和解题过程简单化。如下面所举一例,即是从不同的角度去运用等效模型的方法.题目:如图1所示:一个 U 形管内装有一 The model is divided into physical model and process model. From the perspective of application, it is nothing more than similarity and equivalence. However, in the process of solving physical problems, if the equivalent model thinking method is used properly, some complicated problems can be solved. The settlement process is simplified. As an example is given below, it is a method of using the equivalent model from different perspectives. Title: As shown in Figure 1: A U-shaped tube is equipped with a
