The results show that the effect of Li is to increase the rate of hardening, however, the addition of lithium does not progressively change age hardening and precipitation process of Al--Cu--Mg--Ag alloys with low Cu/Mg ratio, and significant age hardening response only occurs with the addition of 2.0\%Li.

结果表明，在Al--4.0Mg--1.5Cu--0.4Ag合金中添加锂，可以加速合金的时效进程，但其时效硬化效果并不能简单地随着含锂量的增加而逐步加强，只有当锂含量达到2.0\%时，才表现出显著的时效硬化与强化效果。

Based on the horizontal and vertical combination in formal contexts, this paper defines the independent or consistent contexts and lattices in attribute field; and also defines the horizontal addition operation between contexts or concepts and the horizontal union operation between concept lattices. In addition, we prove that the concept lattice of subcontexts horizontally combined is isomorphic to the horizontal union of sublattices of these subcontexts.
