一种基于骨架的水泵性能曲线复原方法---:考虑到编制水泵装置选型及优化方面软件须将大量复杂的水泵综合性能曲线图片数字化后输入计算机，提出了"扫描一细化一取样一拟合"的复原方法，较好地解决了扫描图片线条较粗影响精度、人工取样费时费力的问题.该方法在"水泵优化与选型"软件中得到成功应用.-Based on pump performance curve skeleton--- restoration method: taking into account the selection and preparation of pump system optimization software required to a large number of complex Pump Performance Curve image digitized into the computer, put forward " a detailed scan of a sample of a fit " of the restoration method, can solve the impact of the scanning image line coarse accuracy, time-consuming manual sampling effort problem. The method of"　Pump Selection and Optimization " software has been successfully applied.
