“微元法”是从局部到整体的思维方式,将复杂的问题进行分解,使复杂的过程变得简单.物理学本身就是一门比较复杂难懂的学科,学生学习的过程中,会遇到很多比较繁琐的物理过程,微元法的应用,能够将物理过程分解成几个简单的过程,通过对简单过程的分析,最后整体处理,使学生在解决这一类问题时可以很容易找到切入点,以简单的过程代替繁杂的过程,学生通过这一解题过程,能够增强对物理学习的信心,对物理学习有重要的促进作用.一、“微元法”的解题思路“微元法”指从问题的局部开始研究、进而研究问题整体的一种综合分析的方式.对于一些比较复杂的物理问题,可采 “Micro-element method ” is from the local to the whole way of thinking, the complex problem is decomposed, the complex process becomes simple.Physics itself is a more complex and difficult to understand subjects, the process of student learning, Will encounter many more complicated physical processes, the application of the micro-element method, the physical process can be broken down into several simple processes, through the analysis of the simple process, the final overall treatment, so that students can solve this type of problem can be very Easy to find the starting point, to replace the complicated process with a simple process, the students through this problem-solving process, can enhance the confidence of physical learning, an important role in promoting physical learning. Problem ideas “Micro-element method ” refers to the way from the local part of the problem began to study, and then study the overall problem of a comprehensive analysis of some of the more complex physical problems, recoverable
