Based on dual-strictly diagonally dominant concept for solving linear equations often used in the JOR iterative method is given JOR iterative matrix spectral radius and the upper bound of the new iteration of the convergence criteria, applicable not only to strictly diagonally dominant matrix, also applies to dual-strictly diagonally dominant matrices, the corresponding iterative matrix spectral radius estimates and more accurate convergence of the expansion of the JOR method of selection parameters, and numerical examples to illustrate the results of the superiority.
