【摘要】 由于第二类曲线积分与曲面积分涉及到方向性问题,因此利用对称性来计算较为困难.文中给出了利用对称性计算第二类曲线积分与曲面积分的方法,并证明了方法的可行性,并通过实例表明,此方法有时能起到简化计算的作用.更多还原

【Abstract】 The second kind of curvilinear Integral and surface Integral are concerning orientation,so it is hard to calculate them with symmetry.A good method is provided and its feasibility has been proved.With some cases,it shows that this is exactly a good method to simplify calculations sometimes.更多还原
