物体间的支持力或压力看似简单,但是在实际高一教学中我发现学生比较难掌握.虽然一些教辅书籍提供了一些方法,但是,这些方法往往因为文字比较多,判断起来比较复杂,因此,同学们掌握起来还是有一定难度.就此笔者归纳了一种与教辅书籍相似但又简单的方法,现介绍如下.

The support or pressure between the objects seems simple, but in the actual high school teaching I found that students are more difficult to grasp. Although some supplementary books provide some methods, but these methods are often more complicated because of the large number of words. Therefore, the students still have a certain degree of difficulty in mastering. For this reason, the author has summarized a similar but simple method with supplementary books.
