| 摘 要： | 在原霍尔效应实验的基础上,运用磁场叠加原理,提出用作差法和电位调零法来测量霍尔电压,这两种方法不仅能够消除不等位电势差与环境因素对霍尔效应实验的影响,还能够很好地测量外界环境磁场在霍尔片所在位置处的磁感应强度的大小.

| Abstract: | The Hall voltage is measured using subtraction method and Zero potential method using superposition principle based on original Hall effect experiment,these two methods not only can eliminate the influence of potential difference and environmental factors impacting on the Hall effect experiment but also can measure the size of the magnetic induction in the position of external environmental magnetic field where the Hall probe is. |
