摘要
无穷限反常积分收敛时,其被积函数在无穷远处的极限不一定为零。当对被积函数作某些限制时,其在无穷远处的极限可以为零。
The limit of the integrandf（x） of abnormal integral ,which is convergent in the infinite range of integration,is not certainly equal zero at infinity. When imposed some restrictions on the integrand, the limit can be equal zero at infinity.
