摘要
本文指出：二项展开式中的系数Ｈ数其实就是第二类Ｓｔｉｒｌｉｎｇ数，并通过第二类Ｓｔｉｒｌｉｎｇ数研究了Ｈ数的性质。
In this paper, we are trying to prove that coefficient Number H, in the development formula of binomial, is actually the second type of Strifing Number and by using the Second type of Stirling Number, we have studied the property of Number H.
