| Abstract: | Anthore give a kind of two levels implicit difference scheme for the one order and one space dimensional linear hyperbolic equation with combination difference resolution, and its local truncation error is of order. Then we prove that the scheme is unconditionally stable. Finally, a numerical example shows that the resolution of theoretic analysis is effective. |
