函数f^α（X）的各阶微商表示式及其应用

Expression and Application of Function f~α(x)’ s Arbitrary Order Derivative

讨论了函数ｆα（ｘ） 的各阶微商表示式，获得形式幂级数的一个性质。

In the paper, we obtain an expression of function f α (x) ’s arbitrary order derivative and a theorem on formol power series, and show a new proof of a known combinatorial identity and its generalized results.
