摘　　要：利用积分域的对称性研究了积分计算的简化问题.针对积分域由对称的两部分组成且有方向性,及积分域具有轮换对称性的两种情形,给出了积分计算的简化公式,统一了已有的相关简化运算的形式.Simplified problems for integral calculation were studied by using the symmetry of integral domain. Gave a simplified formula for integral calculation when the integral domain consists of two symmetrical parts and have directionality, as well as the integral domain is translatable symmetry. And the existing related forms of simplified operation were unified.

关 键 词：积分域 对称性 方向性 轮换对称性
