在反常积分习题课教学中，选取适当例题，诠释反常积分与定积分之间的差异。通过变更或补充被积函数所满足的条件，设计相应习题，并最终借助题解说明，在一定条件下，对收敛的反常积分，其被积函数在无穷远处必为无穷小。

This paper discusses teaching improper integral in Exercise Classes .By choosing appropriate examples ,we show the difference between improper integral and definite integral .By changing or adding the conditions of the integrand functions and with some examples ,we show that ,under certain conditions ,the integrand of a convergent improper integral over an unbounded interval is infinitesimal at infinity .
