| 摘 要： | 给出了一种利用霍尔效应测量螺线管磁场的新方法：用数字电压表取代电位差计等诸多仪器测量霍尔电热差，进而计算出通电长直螺线管内轴向磁场的分布，实验证明，该方法测量精度高、稳定性好，克服了以往测量方法的缺点，极大地提高了实验精度和实验效率。

| Abstract: | Digital voltmeters, instead of voltage meters and other instruments, are used to measure Hull voltage and then to calculate the axial magnetic induction distribution in charged straight spiral tubes. This method has been proved to be more accurate and stable and thus improves precision and efficiency of experiments. |
