The problem of set partitions in combinatorial mathematics is conside-red, and the following three points are emphasized:(1) the non-recursivealgorithm for computing the number of partitions of an N-Set, P;(2)the algorithm for mapping the partition vector V to the partition sequencenumber D;(3) the algorithm for mapping the partition sequence number Dto the partition vector V.

本文对组合数学中的集合划分问题进行了一些探索，试图回答下面三个问题：①集合划分方法数P的非递归算法，②划分向量V映射到划分序号D的算法，③划分序号D映射到划分向量V的算法。本文以划分的构造树为基础，加以变换，得到数目树和分块树，由此求得P，以及K块划分方法数P_K。
