Computing of Double Integral for a Class of Finite Element Basis Functions by the Symmetry of Integral Region

本文使用对称性计算一类有限元基函数在非规则区域的二重积分.通过两个算例验证对称性技巧在重积分计算上所带来的极大便利性.本文的内容进一步说明了使用对称性进行重积分计算在其他学科的应用价值.

In the paper,the computing of double integral by using the symmetry technique in some irregular regions for a class of finite element basis functions is presented through two examples,and the application of symmetry technique in calculating double integrals in other subjects is discussed.
