摘要
针对如何简化重积分的计算,提出了利用积分区域的等分原理和积分变元的轮换对称性这两种方法,对表面上不具有对称性,或具有的对称因素不明显外露的情况,通过实例给出了构造对称性的方法,从而简化了重积分的计算.
In solution for multiple integral, two kinds of methods, wherein the equipartition principle of integral interval and transferring symmetry of integral variables are utilized respectively. For some cases such as superficial dissymmetry or unobvious reveal of symmetrical factors, the Construction Symmetry method was proposed through some practical examples.
