摘　　要：为实现主动型氢原子钟脉泽的小型化，对其物理结构进行了优化设计。其中，腔一泡结构、真空系统、C场线圈、束光学系统、磁屏蔽系统均被理论分析和优化设计，并进行了相关的验证实验。双真空结构设计有效地减小了氢脉泽的尺寸。在此基础上，对空间应用主动型氢原子钟的地面样机进行了研制，复合泵技术进一步减小了主动型氢原子钟的尺寸和重量。In order to achieve miniaturized maser of active hydrogen atomic clock, the improvement of the physical package is made. The structure of resonator and storage bulb, vacuum system, constant magnetic field coil, beam optical system and magnetic shielding system are theoretical analysed and designed, and also related verification experiments are made. Double vacuum structure design effectively reduces the size of the hydrogen maser. The prototype of hydrogen atomic clock for space applications is developed, getter technology and composite pump technology further reduce the active hydrogen atomic clock dimensions and weight.
