摘要
根据离心泵的试验数据或性能图上的数据,利用Excel的多元线性回归函数,对离心泵的性能曲线进行多项式最小二乘法拟合。这一方法简便快速,而且还能对回归效果进行显著性检验。
Multiple linear regression function in Excel is used by the author to polynomial fitting of centrifugal pump performance curve with method of least squares according to performance curve of centrifugal pump. Not merely simple, the method can also be used for significance test of regression effect.
