【摘要】 对于某些类型的极限计算问题， 应用大学微积分教科书中介绍的方法计算， 将显得比较赘繁． 本文通过对Ｓｔｏｌｚ 定理的研究， 将给出三个直接的推论并引述其推广的定理， 由此得到几种较为简单的计算方法， 从而解决一些较为复杂题型的极限计算问题更多还原

【Abstract】 The indefinite limit is the difficult point in the part of the limit calculation.As to some types of limit calculation problems,it is rather redundant for calculating by the method introduced in the calculus teaching texbooks.The author gives three direct inferences and quoted its extended theorem by the study to Stolz theorem.Thus,several simpler calculating methods are obtained and the limit calculation problems of some more complex question patterns can be solved.更多还原
