摘要
用一种简捷的方法,讨论了一类满足一定条件的多元函数在任意区域上的积分问题,将任意积分区域简化为常见区域的积分,并给出了估值公式,举例说明了在积分近似计算中的应用及误差分析,同时进行了有关的数值分析,从而更直观地展示了估值公式的意义。
This paper formulate estimate value to the integration of functions of many variables which satisfy some condions by a simply way that converting any region to regular region whose area is equal to the gormer. This paper take some examples in order to show the approximate computation together with error analysis and numerical analysis. These are important to the appication of engineering .
