镧镍储氢技术在氢原子钟中的应用

合金储氢方式现在已被广泛采用，这种储氢方式也可应用于氢原子钟。该文叙述了镧镍合金储氢原理及其在上海天文台氢原子钟上的应用。为了提高可靠性或降低漏气的可能性，已经对该种氢源的结构作了改进。与其它一些储氢方式相比，就其体积与储氢压力等方面而言是非常有优势的。

HYDROGEN ABSORBING ALLOYS APPLICATION IN HYDROGEN MASER

Hydrogen absorbing alloys have been widely used today to store the hydrogen, they also can be applied to the Hydrogen Maser, The paper describes the hydrogen storage principle of the La-Ni alloys and its application in the Hydrogen Maser of Shanghai Astronomical Observatory. To improve the reliability or reduce the possibility of leak, the structure of the hydrogen supplier has been improved. Since this hydrogen storage technology is initially applied in Shanghai Astronomical Observatory hydrogen Maser, further experiment is now being carried out. By contrast with other hydrogen supplier, the alloys hydrogen storage methods have the obvious advantage that the volume of alloys hydrogen storage container can be reduced and the pressure in the container can be decreased.
