摘要
通过2个无穷积分收敛性等价的证明,引出了无穷积分的分部积分算法问题,给出了∫a+∞f(x)dx收敛的充分条件新的证明方法.
Leaded out issue in divisional integral algorithm about infinite integral through the demonstration of equivalence between two infinite integral convergence. Given a new prove of the sufficient condition for the convergence of ∫^＋∞α f（x）dx.
