选择三个不同量级的电阻，分析触点不同位置和两种求平均值的数据处理方法对测量结果的影响。测量结果表明，触点位置直接影响电阻测量的准确度。当触点位于电阻丝的中间区域时，触点位置对测量结果的影响较小，而在电阻丝两端区域影响较大。在数据处理方法方面几何平均算法要优于算术平均算法。

Choosing three resistors with different magnitudes,the influences of contact points and the different data processing method on the measuring results are discussed. The results show that contact position directly affects the accuracy of resistance measurement. When the contact points are in the middle area of the resistance wire,contact points have less effect on the measurement results, while there is a big error when the contact points are in the both ends of region of resistance wire. Meanwhile,the geometric mean algorithm is superior to the arithmetic mean algorithm.
