Preissmann四点时空偏心隐格式思想在二维数学模型中应用初探

Application of the Preissmann Difference Scheme to the 2-D Model (preliminary study)

利用Preissmann四点时空偏心隐格式差分方法的基本思想,推导出二维对流方程的差分格式,并利用本差分格式对简单二维对流方程进行了求解,得到了较好结果。

Applying the Preissmann Difference Scheme, the difference scheme of the 2-D convection equation is developed, and then using this scheme to resolve this equation and had got a good resuh.
