| 摘要: |
| 基于零磁环境下，以空间主动氢脉泽对C场组件实际功能要求为设计依据，首先借助电磁理论,同时兼顾工程设计确定中心场及补偿场线圈的绕制方法及圈数;其次通过通电螺线圈的经验公式计算获得目标均匀静磁场所需要的稳恒电流；最后借助仿真优化及实验验证，确定中心场及补偿场线圈电流分别为0.378mA和0.259mA时可实现小于1%的场不均匀度，由此引起的氢钟磁场不均匀频移可以忽略。 |

| Abstract: |
| Based on the requirement for hydrogen maser design constraints，the C-field is designed without considering the effect of magnetic shield in this paper.First，winding coil method and number of laps are gotten from the basic electromagnetic theory and engineering design point of views，then the target steady current which can generate a uniform magnetic field is calculated by Biot-Savart law，and finally when the main and auxiliary coil current are set at 0.378mA，0.259mA respectively by numerical calculation，simulation and experiment，the magnetic field inhomogeneous is less than 1% which can be neglected. |
