本文研究了能量在几十eV范围内的氢离子与0.1mm厚铌膜的相互作用。研究了膜入口侧非金属杂质（氧、碳和硫）对氢气再放出、截留和渗透的影响。在氢离子轰击过程中，通过化学活性气体（氧气、乙炔和硫化氢）作用于试样，使非金属膜在实验过程中持续保持。特别强调的是，由于非金属覆盖层，以及离子诱导的低能氢离子再发射的特性，达到和坚持的超渗透性制度。
The interactions of hydrogen ions in the energy range of tens of eV with a 0.1 mm-thick niobium membrane have been investigated. Effects of non-metallic impurities (oxygen, carbon and sulphur) at the membrane inlet side on hydrogen reemission, retention and permeation were studied. The non-metal films were continuously maintained during the experimental runs through acting on the specimen with chemically active gases (oxygen, acetylene and hydrogen sulphide) in the process of hydrogen ion bombardment. A particular emphasis was placed on reaching and upholding the superpermeability regimes due to the non-metallic overlayers, as well as on the peculiarities of the ion-induced reemission by the low energy hydrogen ions.
