摘　　要：采用正电子湮没技术来初探氢与ＹＢａ２Ｃｕ３Ｏδ超导体中央空穴和氧的作用，并运用溅射中性粒子质谱仪（ＳＮＭＳ）来检测氢在ＹＢａ２Ｃｕ３Ｏδ中的渗透情况，以了解ＹＢａ２Ｃｕ３Ｏδ中的位错、空穴缺陷等微观信息。In this paper , in order to find out the microscopic information about dislocation and defect, the positron-annihilation technique has been used to investigate the effect of hydro- gen on oxygen hole in YBa2Cu3Oδ superconductors, and then with the help of the sputtering neu- tral-particles mass spectroscopy (SNMS ) the permeability of hydrogen in YBa2Cu3Oδ can also tested.
