分析LaNi5氚老化过程的热力学平衡关系,根据LaNi5贮氚过程平衡状态下的热力学函数,导出了能够完整描述整个实验范围P-C-T关系的平衡公式。利用P-C-T平衡公式对不同材龄的LaNi5Dn在不同温度下平衡压力与贮氚量的变化曲线进行了拟合分析。结果表明,拟合结果在大部分温度下与实验数据符合情况较好,同时验证了理论的正确性。
Based on the thermodynamic functions of LaNi5 during the process of tritium storage and storage, the equilibrium equation describing the P-C-T relationship of the whole experimental range is derived. The P-C-T equilibrium formula was used to fit the curve of the equilibrium pressure and the tritium storage volume of LaNi5Dn at different temperatures. The results show that the fitting results are in good agreement with the experimental data at most temperatures, and the correctness of the theory is verified.
