在霍尔效应测量霍尔灵敏度的传统实验中，通常考虑四种副效应.本文基于实验数据，评定了副效应对霍尔灵敏度准确度的影响，证实不等位电势差这一副效应的作用最为显著，其它副效应可以忽略. 进一步，基于霍尔电压和不等位电势差随工作电流和外加磁场大小的变化存在不同的变化规律，提出了利用线性最小二乘法和二元二次非线性模型测定霍尔灵敏度的两种新方案，将传统实验中利用对称测量法消除系统误差的策略提升为从差异出发寻找解决问题的策略.

In traditional Hall effect experiments for Hall sensitivity measurement, 4 side effects are usually considered. Based on the experimental data, the influence of side effects on the accuracy of Hall sensitivity is valuated. It is confirmed that the voltage drop due to unequal potential is most prominent, while other side effects are negligible. Furthermore, considering that the Hall voltage and the voltage drop due to unequal potential vary differently with the magnitudes of the working current and the external magnetic field, two new schemes, i.e., applying linear least squares method and binary quadratic nonlinear model, respectively, for measuring Hall sensitivity are proposed. Then, the strategy for eliminating system errors with symmetric measurement method in the traditional experiment is improved to a strategy of solving problems from differences.
