【摘要】 应用算子分裂思想将矩形明渠均匀流方程分裂为两个简单算式 ,通过耦合方法建立了整个定义域内的统一近似算式 ,该算式结构简明 ,计算方便 ,精度可达 10更多还原

【Abstract】 According to operator splitting theory,the equations for uniform flow of rectangular open channels can be separated into two simple formulas.And through coupling method,the approximate formula in the whole definition domain can be obtained.This approximate formula is simple,convenient for calculating,and its precision reached is 10 -5 .更多还原
