| 摘 要： | 不定式（待定型）极限运算是历年来考研数学必考的题目，罗比达法则是解决这类极限运算的有效工具．但罗比达法则也有它的局限性．如果把等价无穷小替换和罗比达法则结合起来用，不仅可以达到事半功倍的效果，而且有时还可以解决罗比达法则不适用的情形．

| Abstract: | Infinitive limit operation is an indispensable part in mathematics entrance examination to postgraduate study and L’Hospital Rule is an effective tool to solve this kind of operation.However,L’ Hospital Rule also has its limitations.And the combination of infinitive limit operation and L’Hospital Rule can help yield twice the result with half the effort and help solve problems that L’Hospital Rule can’t do. |

| Keywords: | mathematics examination to postgraduate limit L 'Hospital Rule infinitive limitoperation |
