摘　　要：微积分是高等数学的基础,学习好这部分知识对后继课程的学习格外重要。在微积分的学习中,学习者要经常面对大量的计算。如果找不到合适的方法,会让学习者无所适从;掌握了解题方法对深刻理解微积分起到事半功倍的作用。本文结合教学实际,列举出一些具体问题,谈一谈利用"换元"的方法,来解决实例问题。Calculus of higher mathematics is foundation,study well this part of knowledge on subsequent course of study are particularly important.In the calculus of learning,learners should often face a number of calculations.If you can＇t find the right method,can let learners bewilder;Master understand questions method of profound understanding calculus play twice the result with half the effort effect.This paper combining with the teaching practice,this paper lists some concrete problems,talk about using ＂change yuan＂ method,solves the problem.
