重积分在积分不等式证明中的应用

摘要

Double integral plays an important part in the proof of integral inequality .In this paper ,four ways are presented to solve the problems of integral by means of double integral ,and these four ways are applied to the proof of integral inequality .%重积分在积分不等式的证明中占据了重要的地位，笔者例举了利用重积分证明积分不等式的四种方法，并将这四种方法应用于积分不等式的证明。
