摘要
根据最小二乘法原理 ,采用曲线拟合方法 ,对矿井主扇性能测定的实际特性曲线数据进行逐次拟合 ,通过比较得出风机特性曲线采用 5次多项式拟合效果最佳。
Based on the principle of least squares techniques,adopting the method of curve fitting,successive fit is proceeded to the data of actual characteristic curve obtained by the performance measurement of the main fan and by comparison,a conclusion is drawn that to the characteristic curve of fan,adopting quintic multinomial to fit can get optimal effect.
