微元法是高中物理中的一种基本方法,许多问题都用它来处理,但学生由于在高中阶段对微元及微积分的概念了解的不是很透彻,因此在用微元法处理一些物理问题时会遇到很大的问题.针对这种情况笔者认为在高中阶段的教学中,鉴于高中生对微分思想还不够深入,在处理实际问题时,可以不用微分思想解决的问题,我们可以尽量的回避.可以引导学生用更加容易接受的平均值思想来解决,特别是在许多磁场的问题中,用平均值思想就使学生容易接受得多.下面我们就用一些实际 Micro-element method is a high school physics in a basic method, many problems are used to deal with it, but students in the high school because of the concept of micro-elements and calculus is not very thorough understanding, so the use of micro-element method to deal with some physics In view of this situation, I believe that in the teaching of senior high school, given that senior high school students are not yet sufficiently advanced in differential thinking, we can try our best not to solve the problem with the differential thinking when dealing with practical problems Can be used to guide students to use a more acceptable average thinking to solve, especially in many magnetic problems, the average value of thinking makes it easier for students to accept the following we use some actual
