定积分保号性质的推广和应用

The Spreading and Application of the Monotony Quality of the Define Integral

将定积分的保号性及其推论作进一步的推广,主要结果在文中的定理2和推论2中给出.从而,应用定积分的保号性证明不等式或比较定积分大小时,“等号”、“不等号”的取舍就有了理论根据.

This paper has furthermore spreaded the monotony quality and deductions of the define integral, which results is given in theorem 2 and deduction 2. While in the application of its monotony to testify the inequality or compare define integral, the selection of equality sign and inequality sign gets a theoretical foundation.
