摘要
在水泵的选型过程中,通常采用多项式的最小二乘法来拟合水泵性能曲线。介绍了根据水泵厂家提供的典型数据,利用Visual Basic语言编制程序来实现水泵性能曲线的自动绘制。
In the course of type selecting of the water pump, the mathematic model of least square surface fitting is utilized for the drawing of the pump＇ s characteristic curve. According to the typical data offered by the producer and with the utilize of the Visual Basic language, the pump＇s characteristic curve will be automatically drawn.
