Based on the basic principle and process of Al Cu alloy's Age strengthening,there is a step further theoretical analyses on age strengthening with systematic free energy,and hole formation and action,and disloction movement.

在AlCu合金时效强化基本原理和过程的基础上,用系统自由能变化、空位形成与作用、位借运动等对时效强化作了进一步的理论分析。

1mol·dm-3KNO3 The results show that the stability of binary complexes accord with the Irving-Williams order of metal ions for the same ligand and linear free energy relationship(LFER) between stability of complex and basicity of ligand exist nicely for each metal ion.

结果表明，对于同一种配体，配合物的稳定性均符合金属离子的欧文—威廉序；对于同一种金属离子，在配合物稳定性与配体的碱性之间均存在良好的直线自由能关系。
