| Abstract: | This paper gives a meticulous method for treating the singular integral. In order to better fit the space curved surface of arbitrary shape, the curved surface is discussed into trianglar elements of curved surface . The generalized integral can be calculated by using similar search method. The computed results shows that the method has surperier accuracy. The numerical simulations are successfully made for a great deal of problems with practical value and the satisfactory results are obtained. |
