| 摘 要： | 本文探讨了水泵能量试验及汽蚀试验曲线拟合的问题。提出采用改进的多项式最小二乘法对泵能量试验曲线进行回归处理，并在此基础上，探求了一种协调拟合中出现的曲线光顾与拟合精度这一对矛盾的方法。关于汽蚀试验曲线的拟合，则采用了一非线性拟合的数学模型。对两模型都结合相应实例分别加以了说明，并给出了处理后的试验曲线。

| Abstract: | The paper discusses some problems of pump energy test and cavitation test curve - fitting.Present to use an improved, method of polynomial minimum squares to process pump energy curve in regression on the basis. A method compromising the contradictory between fining precision and curve smooth is analysed. Anonlinear fitting math model is adopted for pump cavifation Both malels, are respsctively illustratedwith correspondent instances, and gives the test curves fitted in the final. |
