【Abstract】 Recent years the development and applications of modern getters has been making a great progress. They are become more and more important in vacuum technology. This paper presents the absorption machanism and the equilibrium theory on the absorption and de--absorption of getters for hydrogen and its isotopes. The recent development of both evaporable and non--evaporable getter and their applications are discussed also.更多还原
