【Abstract】 A highly accurate and unconditionally stable three level implicit difference scheme is proposed for solving second order hyperbolic partial differential equations. In order to reduce computational efforts, an efficient parallel iterative explicit method based on this difference scheme is established, and an example is presented to illustrate practicality and usefulness of this parallel iteration method.更多还原
