两收敛且等值的无穷限广义积分变量代换的存在唯一性

The Existence and Uniqueness of the Variable Replacement in two Convergent and Equal Improper lntegral in Infinite Interval

本文讨论两个收敛且等值的无穷限广义积分变量代换的存在性与唯一性，文中提出并证明了在一定的条件下，这个代换是存在的，也是唯一的。

This paper concerns the existence and uniqueness of the variables re-placement in two convergent and equal improper integral in infinite interval.The existence and uniqueness of the replacement are mentioned and proved with cen-tain conditions.
