摘要
本文用Stone-Brian隐式有限差分方法,结合实例对恒定非均匀流污染带计算,进行数值试验。认为方法切实可行,较之解析解有其显著优点,文中就计算及程序设计提出了应注意的问题.
The analytical solution of the method of dimensionless transverse-cumu- lative discharge is usually derived in calculation of transverse spreading of a plu- me in steady nonuniform flows, but the method can not describe channel irregul- arities and the variation of discharge intensity in situation, and so on. This paper employs Stone-Brain implicit finite difference method and an example shows this method is feasible and excellent, Some problems on program design and computat- ion are also discussed.
