The results show that the alloys are composed of LaNi5 as matrix and LaNi3 as secondary phase. With the increasing Sm substitution for La, the unit cell volume of matrix of the alloys shrinks linearly and both the hydrogen storage capacity and discharge capacity decrease. When the Sm substitution is 0.1, 0.2 and 0.3, the discharge capacity decreases from 380 mA·h/g to 370(362), 355(334) and 329(295) mA·h/g, respectively. However, the rate performance and cycle stability is improved. After 100 cycles, the capacity loss decreases from 20% to 18%(17%), 16%(14%) and 13%(11%).

结果表明：该合金是由LaNi5主相和LaNi3第二相构成；随着Sm取代La量的增加，合金主相单胞体积线性收缩，合金储氢量和放电容量减小，当Sm取代量分别为0.1、 0.2、 0.3时，合金容量由380 mA·h/g分别减小到370(362)、 355(334)、 329(295) mA·h/g，但高倍率放电能力和循环稳定性得到改善， 100次循环后的容量损失率由20%分别降低到18%(17%)、 16%(14%)、 13%(11%)。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
