摘　　要：介绍构建风压特性拟合曲线的基本思路,通过标准差和确定数判断拟合曲线的准确性,用实例分析不同次数拟合方程的精度,结果显示随着拟合次数的升高,拟合精度也随之提高,可以给矿井通风机风压特性的研究带来参考。Describes the basic ideas to fit the pressure characteristic curve, and curve fitting accuracy is determined by the standard deviation and the number. Analyze different fitting equation′s precision,and the result shows that with the increase in the number of fitting equation, the accuracy also increases, to give reference to the study of mine ventilator pressure characteristic.
