| 摘 要： | 摘要：第二类stirling数5（n，n-L）是分配问题中实用价值很高的分配数，计算起来均较为繁琐，在限制条件n≥M下，对于n与L的取值不同目前已出现一些不同的计算公式，但对于n、M、L之间的内在联系还缺乏较深的认识，通过对n、M、L之间关系的讨论，揭示了它们的内在规律，并给出了S（n,n-L）的一个计算公式．

| Abstract: | The Stifling numbers of the second kind is of very high practical value in the distribution of the ap- portionment, but it is very complicated in calculating. Under the constraint of n≥M , there are already some formulas with different values of n and L, however, the intrinsic relationship of n,M and L is still lack of deep understanding. Based on the discussion of the relationship of n, M and L, this paper reveals their inter- nal disciplines and gives a formula to calculate. |
