摘要
一种用来装备中国VLBI网络的新型氢脉泽标准已在上海天艺台研制成功。这种新型氢脉泽标准是一种坚固的可靠的和可搬运的小型氢钟。本文将描述它的机械和电子学设计特点,并与上海天文台早期制造的氢钟进行了详细的比较。文章给出了新的小型氢钟的初步测试数据和预期的稳定性能,并且展示了这种新型氢钟在制造过程中的一些照片。
A new hydrogen maser for VLBI-network in China has been developed at Shanghai Observatory. The new maser is a rugged, relible and transportable hydrogen maser. This paper describes the mechanical and electronics design philosophy of the new maser, and comparisons with previous masers made at Shanghai Observatory are detailed. Preliminary test data and projection of stability performance are included, as well as photographs of the new maser system during the construction phase.
