摘要
应用构造求和相消与待定系数建立关于等差数列ak各项平方的倒数之和k=m∑a1k2的上下限估计,加强了涉及等差数列ak的若干已有结论。
The estimated bounds of （^n∑k=m）1/aξ , the sum of reciprocals of the square of each part of arithmetical series {ak},have been established by applying the structured summation approach and the method of undetermined coefficients. This conclusions of series of equal differences involved have been strengthened.
