Grids based on an even number of grid columns can suffer from too much symmetry if text and graphics are confined to individual or doublegrid columns throughout.
基于偶数的栅格可能会遭遇过于对称的困扰，假如文本和图形总是占据1 - 2个单元格的话。

The governing equations are discretized on uniform grids using the FiniteDifference method, and a doublegrid method is used for the mesh slice to save the time.
采用基于均匀网格的有限差分离散控制方程，为了节省时间，在网格剖分时还采用了双重网格法。
