摘要
根据莱思德兹(Leendertse)定义的两个收敛准则因子R_1、R_2,针对一维圣·维南方程组,从理论上对“T形”隐格式的收敛性问题进行了讨论,基本上完整了“T形”隐格式的理论研究,并与目前国内外常用的四点偏心Preissmann格式进行了比较,所得结果可供实际应用参考。
A theoretical study is made on the convergence of T-shape implicit scheme used in st. Venant equations according to the two convergence factors ( R_1, R_2 ) given by Leendertse and is compared with the four points general Preissmann scheme widely applied in the practical engineering in the world. The results may be available for referrenee in practice.
