微元法,就是将研究对象的运动过程进行无限细分,从其中选取某一微小单元进行分析和讨论,从而得出结论的方法。微元法是利用微积分来处理物理问题的一种解题方法,若教师在中学物理教学中恰当地选择一些问题,引导学生利用微元法进行针对性的分析,对培养中学生的思维能力和综合分析能力是有益的。如教材中出现一物体做匀变速直线运动的速度-
Micro-element method, that is, the object of the exercise process unlimited subdivision, from which to select a small unit for analysis and discussion, and thus draw conclusions. Micro-element method is to use calculus to deal with physical problems, a problem-solving method, if teachers in middle school physics teaching appropriate choice of some problems, guide students to use micro-element method for targeted analysis of the training of middle school students thinking ability and Comprehensive analysis of the capacity is beneficial. Such as materials appear in an object to do variable speed linear motion speed -
