摘　　要：组合恒等式在组合数学中占有重要地位,它有多种证法.本文舍弃了它的常见证法,另外运用了求导法则和概率方法对几个重要的组合恒等式给出了直观简洁的证明.Combinatorial identity is very important in combinatorial mathematics,while many methods can be used to prove.In stead of usual approach,this paper uses two new methods of derivation calulas and probability method,and gives a direct and simple solution to several important combinatorial identities.

关 键 词：组合恒等式 求导法则 概率方法
