用初等方法推导伯努利数的显性计算公式

The Derivation of the Explicit Formula of Bernoulli Number by Elementary Method

首先给出了正整数幂和的显性计算公式,并用数学归纳法证明了相关的结论,然后从中得出了伯努利数的显性计算公式.

First the explicit formula for positive integer＇s power sum is given,and the relevant conclusions are then proved through the use of mathematical induction,from which an explicit formula of Bernoulli number is thus worked out.
