摘　　要：氢原子频标中贮存泡内壁的成膜状态直接决定跃迁信号的产生及指标,贮存泡的涂敷和烧结工艺成为氢原子频标研制中的一项关键技术。通过分析聚四氟乙烯和聚全氟乙丙稀树脂的热处理特性以及氢原子频标对成膜的要求,分别针对蓝宝石氢原子频标和被动型氢原子频标贮存泡的特点,给出了相应的涂敷和烧结工艺。实际氢原子频标系统的测试表明,该涂膜工艺满足氢原子频标的使用要求。The states of covering on storage bulb inner wall of Hydrogen maser affect the producing and performance of transition signals,and the coating and sintering process is one of the key techniques in Hydrogen frequency standard system. By analyzing the heat treatment characters of PTFE and FEP res- ins,and the requirements of film,the coating and sintering techincs are given for active Hydrogen maser and passive Hydrogen maser, respectively. The applications on hydrogen masers show that the techincs can well satisfy the Hydrogen maser use.
