1·In this paper, the way of solving the limit of indeterminate form problems by using derivatives is changed to that by using difference, and two basic theorems similar to L'Hopital's rule are given.

求不定型极限问题是高等数学中的一个重要内容，而洛必达法则是求这种极限的一种有力手段。

2·This method is expressed in matrix form, and is applicable both for statically determinate and indeterminate problems. The method is will suited to computer-based calculation.

这里介绍的传递矩阵法采用矩阵形式表达，不管是静定问题还是超静定问题，都使用同样的程序进行计算，非常适合上机计算。
