摘要：

The H-1 and H-2 spin-lattice relaxation times in the monohydride phase of the V-H-D and Ti0.1V0.9-H-D systems have been re-analyzed by Bloembergen-Purcell-Pound (BPP) equations with a log-normal distribution of correlation times, and the obtained parameters have been compared with those of the Ti0.33V0.67-H-D system. The mean activation energy and the magnitude of the distribution of H and D diffusions are discussed in relation to the metal compositions, the hydrogen site, the crystal structure and the [H]/[D] ratios.
