| Abstract: | This paper examines the linear system Ax=b when A is a L-matrix.Given two-stage iteration,a comparison was drawn between spectral radii of AOR and preconditioned AOR methods,aiming at more accurate results of R1-factor of the outer iteration of two-stage iterative. |

| Keywords: | two-stage iterative L-matrix AOR method preconditioned AOR method spectral radius |
