| 摘 要： | 根据积分区域和被积函数情况，用曲线（或直线，射线）分割积分区域，构建区域元素一元微分，把二重积分直接化为单积分．此种方法可简化二重积分的计算，有必要编写入微积分教材中．

| Abstract: | As the circumstances may require, divide the integral domain with straight or curved lines to construct properly a first order differential form based on the area elment, thus, some double integrals can be changed into simple integrals. Exmples are given to show how the method words. |
