根据工程数学最小二乘法的基本原理,建立了离心泵性能曲线方程的两种数学模型。经计算机测试,验证了数学模型的精确性。这两种拟合法适用于各种离心泵性能曲线的拟合。
According to the basic principle of least square method in engineering mathematics, two mathematical models of centrifugal pump performance curve equation are established. Computer tests show the accuracy of the mathematical model. These two fitting methods are suitable for the fitting of various centrifugal pump performance curves.
