【Abstract】 We present a kind of implicit characteristic-difference schemes, and provethat this kind of schemes is nnconditional stable for systems of linear eguationswith constant coefficients. The scheme is used in computation for one-dimensionalunsteady flow, and uumerical results are presented, showing the effectiveness of thescheme.更多还原
