摘要
矿井主通风机性能曲线模型是关于矿井通风机风量关系的多项式模型 ,将风量的各因次幂替换后可以转化为多元线性模型。运用曲线拟合的最小二乘法对其多元线性模型进行系数估计后 ,再在给定的回归精度 (线性显著水平 )条件下 ,对其回归模型及回归系数进行显著性F检验 ,最终所得的通风机性能曲线模型方程 ,经实例计算表明 ,具有较高的精度。
The performance curve model of mine main fan is the polynomial model about the air quantity of mine fan ventilating relations,and can change to multi_cell the linear model after each dimension power with the air current is replaced.The least_square method using the curve to draw up closing is carried on the coefficient to his linear model of many units after the estimation,and under preset precision the returning (linear notable standard) condition,returning the model and returns the coefficient to carry on F outstanding check to his,the mine fan characteristic curve model equation of final what one has gained or acquired indicates through living example calculation,and possesses the higher precision again.
