The Existence and Uniqueness of the Variable Replacement in two Convergent and Equal Improper Integral on Unbounded Function

本文讨论两个收敛且等值的无界函数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。

This paper concerns the existence and uniqueness of the variables replacement in two convegent and equal improper integral on unbounded function. It has mentioned and proved the existence and uniqueness of the replacment under certain conditions.
