摘要
文中构造了求解含沙量分布沿程变化的稳定性好、精度较高的差分格式(Douglas格式),并通过一个具体的数值例子说明了计算的方法,体现了这种格式的实用性和优越性.
A kind of difference Scheme ( named Douglas scheme) was set up according the discussion of the numerical method on diffusion equation for suspended sediment, and an example showing the calculation process was given in this paper.
