摘　　要：介绍了一种为实现主动型氢脉泽小型化而设计的双真空结构氢脉泽的最新研究进展，并将其与上海天文台SOHM-4型主动型氢原子钟进行了比较。其物理尺寸和重量较原来有较大幅度减小，磁灵敏度和温度灵敏度指标均有所提高，长期稳定度和日漂移率优于预期。The recent research of SHAO＇s new double-vacuum- structured active hydrogen maser to achieve itsminiaturization is described. Compared with SOHM-4 active hydrogen maser, its physical size and weight are substantiallydecreased,the magnetic sensitivity and temperature sensitivity are improved, the long-term frequency stability and dayfrequency drift are better than expected
