摘　　要：从一个求函数极限的例子引出两个与罗比达法则有关的相互矛盾的结论;通过对柯西中值定理的深刻剖析,找出了错误的原因;在此基础上,对罗比达法则的条件进行了改进.Two contradictory results relating to L＇ Hospital ruler were gain by studying an example which dealt with ：he limit of a function. The cause of the error was found by analyzing Cauchy middle value theorem. The improvement of ：he condition of L＇ Hospital ruler was put forward.
