英文摘要:
      Using Petrov-Galerkin technique for first-order hyperbolic equations from so call "unit CFL property", K. W. Morton and A. K. Parroit Presented EPG and CNPG methods and so on. In this Paper some shortcomings on the accuracy and stability of those two methods mentioned above are analyzed. By changing choice of test function we have given a scheme with the best accuracy, improved stability conditions, and simplified calculation of hyperbolic equation system.
