| Abstract: | Using the solid angle that a closed surface opens to an outer point of that is zero,the integration for lateral surface of a cylinder has been changed into the integration for the bottom surface under the cylindrical boundary condition,which has been turned into elliptic integration. |

| Keywords: | Solid angle Integral equation Elliptic integration |
