排灌工程的经济效益有多项考核指标并有多种计算方法,但一般比较繁杂。大规模进行换泵改造时仅用静态法分析,总体精度太差(如单个或少数小型泵站改造可采用静态法以减少计算工作量)。现结合我们在曹
The economic benefits of irrigation and drainage projects have a number of assessment indicators and a variety of calculation methods, but generally more complicated. Large-scale transformation of the pump only static analysis, the overall accuracy is too poor (such as single or a small number of small pump station transformation can be static method to reduce the computational workload). Now we are in Cao
