【Abstract】 The finite element equation, which the three dimensional three component wave equation satisfies, is derived if the domain of an arbitrary anisotropic medium is divided into hexahedron elements and a linear interpolation function in each coordinate direction is used. The finite element equation is a general formula because it is also suitable for two dimensional three component wave equations.更多还原
