二重积分的计算方法

The Calculation Method of Double Integration

主要探讨直角坐标系下二重积分的计算方法与技巧,将积分区域分成X型和Y型两大类,并且给出了两种类型的几何特点,分别列出了二重积分的累次积分的公式,最后举例加以说明。

This paper examines the double integration of the Cartesian coordinate system calculation methods and techniques, the integration area into X - and Y - type two categories, gives the two types of geometric features, breakdown of the double integral of the integral equation, finally, gives an example to illustrate this.
