摘　　要：编制有关水泵及水泵装置选型设计方面的软件,需将大量的、形状复杂的水泵综合性能曲线数字化以后输入计算机,在经过运算后,还需将数字化的曲线还原为图形。为保证曲线数字化的快速准确,文章提出了“扫描仪输入法”;为保证曲线还原的准确,又提出了“曲线尺连线法”。这两种方法在“水泵装置优化选型设计”软件中得到了成功应用。Exchanging analogue values and digital values of pump performance curves is a fundamental work to various pump system in designing software. The way to input shapes of pump performance curves and its conversion are key to various software. Practical way to digitize analogue values with the help of scanner and to converse digital values to analogue values based on the rule of curve ruler is given. The new method is well fit to Aid Optimum Hydraulic Design of Pump System and successfully applied.
