化自然数的方幂和为多项式

A Method of Converting into Polynomials the Sum of Natural Numbers’Third Power

本文首先利用Ｏ．Ｓｔｏｌｚ定理证明了自然数的方幂和能够化为多项式。在此基础上，给出了一个化自然数的方幂和为多项式的简便且直观的方法。

This arricle,on the basis of O.Stolz theorem,proves that the sum of naturl numbers’third power is capable of being converted into polynomials.Following the conslusion,a simpleand conveint method of conversion is provided.
