A very shot-cut equation  which is called symmetrical equation of diffracted wavevectors by us  is presented. It makes the number of Green's function expansion terms shorter and simplifies the integral kernel by taking into account its symmetry. Take the grating in Littrow mount for computing example  because of applying this equation  the computation cost of integral theory which has good convergence  is shorten to 1/2 to 2/5. This work modifies the integral theory and improves its computing speed. (2012) Trans Tech Publications  Switzerland.
