将不均匀材料网络化用等效电源的方法根据基尔霍夫定律得到了不均匀材料样品的霍尔系数的较为一般的表达式应用该结果可以方便地计算不均匀材料样品的霍尔系数，而双层模型和三层模型是此表达式的特例 Using the equivalent power source to network non-uniform materials, a more general expression for the Hall coefficient of an inhomogeneous material sample is obtained according to Kirchhoff’s law. Using this result, the Hall coefficient of an inhomogeneous material sample can be easily calculated , While the double and triple models are a special case of this expression
