| 摘 要： | 本文用n－1结点法对α－Fe2O3系列气敏材料电阻值随加热电流变化规律做了拟合，并将结果与用最小二乘法以及文献1]所得的结果作了分析对比，发现用R＝AIFe－Blm公式描述此规律与实验结果更为吻合。文中所述的n－1结点法对其它已知曲线形式的实验数据的处理具有普适性。

| Abstract: | The author fit of the resistance of α-Fe2O3 Series gas-sensitive meterialschang law with electric current, contrast the results by using least square method and document 1],discover the results by used R = AIFe-BIm is mor coincident with the experiment.The method. is universality for treatment of experimental data, which must know the form of curve. |
