中文摘要：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。
英文摘要：The thermodynamic equilibrium relationship of the aging of LaNi5 tritium storage was analyzed. The equilibrium formula describing P-C-T relationship for whole experimental data was derived. The experimental P-C-T relationship was analyzed using the equilibrium formula. The results show that the fitting results agree with the experimental results essentially. And the validity of theoretical means is tested.
