摘要：

Both the solubility and the mobility of hydrogen isotopes in metals and alloys are considered. The local mode vibrations of the hydrogen isotopes are identified as the origin of isotope effects and are discussed with respect to octahedral and tetrahedral interstitial positions. Deviations from cubic symmetry are briefly mentioned in connection with interstices in group Vb metals, intermetallic compounds and amorphous metals. Isotope effects in hydrogen mobility are shown to be qualitatively explained by the transition state theory.
