摘要
建立了第2类 Stirling 数与组合数之关系.使得第2类 Stirling 数成为组合数的线性组合.从而在某些时候优化了第2类 Stirling 数的算法,同时完善了"一类与多项式相关的组合恒等式."
The relations between the second kind of stirring number and the number of combination have been built.The second kind of stirling is transformed into the linear combination of the number of combination.Sometimes a successful method to simplify the counting of the second kind of stirling number and the number of combination has been established.Also,one class of combination identical relation related to the multiomial is perfeeeted.
