首先利用初等方法讨论了关于正整数n的r次幂因子函数与欧拉函数的复合函数的均值,然后用解析的方法研究了其推广形式,得到了两个有趣的渐近公式。
By using the elementary method to discuss the mean value of the composite function involving the r-th power and the Euler' function,moreover,research it's promotion formula using the analytic method,two interersting asymptotic formulas are presented in this paper.
