摘要
考虑两无穷区间上的广义积分交换次序定理的充分条件的问题,指出了经典定理的充分条件过于严格.运用函数列积分极限理论结果,对经典严格的充分条件在表述上给予了改进,从而得到在广泛条件下的广义积分交换次序定理,通过实例说明应用.
While the sufficient conditions for improper integrals exchange theorem on infinite interval areusually considered in their practical application,some strict requirements of them are pointed out in this paper.The description of these requirements is improved by the results of the limit theory of function column integrals.The improper integrals exchange theorem with a wide range of conditions is given,and its validity and feasibility isproved by an application example.
