摘　　要：设计了用Ｎｄ替代Ｌａ的系列Ｌａ１－ｘＮｄｘＢ５合金，并分析测试了不同含量Ｎｄ的储氢合金的性能。实验发现，Ｌａ１－ｘＮｄｘＢ５合金的晶胞体积与ｘ呈线性关系；平衡氢压与ｘ呈曲线关系；吸氢量与放电容量在ｘ＝０．２最高；The serials of La1-xNdxB5 alloys replacing La with Nd were designed.The performance of hydrogen storage alloys with different Nd content was analysed and tested.It is found that the cell volume is linear with x,the equilibrium pressure is curve relation with x,the hydrogen absorption and recharge capacity are high as x is 02,the recyclelife increases with Nd content.
