【Abstract】 The Du Fort Frankel difference scheme is modified by the Richardson difference scheme. This paper generalizes the two dimensional difference scheme from the one dimensional difference scheme. It not only gives the consistency condition of the two dimensional Du Fort Frankel difference scheme, but also proves the absolute stability of the difference scheme.更多还原
