| 摘 要： | 研究了用3组轴线相互垂直的线圈组成的磁场屏蔽系统。通过毕奥-萨伐尔定律并借助Matlab软件，分 析比较了矩形线圈和圆形线圈两种屏蔽系统的磁场分布情况。实验数据表明矩形线圈屏蔽系统的性能要略优于圆形线圈屏蔽系统。其结论可应用与原子陀螺、电子显微镜等器件的设计中。

| Abstract: | A magnetic shield system composed of three mutually perpendicular coils was studied. Biot - Savart Law is applied to analyze and compare the magnetic field distribution of rectangular shield system and circular shield system with the help of Matlab. The experiment data show that the performance of rectangular shield system is slightly better than that of the circular shield system. The conclusion can be applied in the design of atomic gyroscope, electron microscope and so on. |
