我们制备了熔纺（Ni 0：6 Nb 0：4）100-xZr（x 1/4 0 ~ 40 at%）等非晶态合金膜，并研究了氢通过这些合金膜的渗透。Ni-Nb-Zr非晶结构中的原子间距随着Zr含量的增加而增加。Ni-Nb-Zr非晶合金的晶化温度随Zr含量的增加而降低。氢气流量随着温度的增加或膜两侧氢气压力的平方根差的增加而增加。在较高的温度（673 K）或较高的氢压差（550 Pa 1=2）下，氢的流动更加严格
We prepared the melt-spun (Ni0:6Nb0:4)100� xZrx (x ¼ 0 to 40 at%) and other amorphous alloy membranes and examined the permeation of hydrogen through those alloy membranes. The interatomic spacing in the Ni–Nb–Zr amorphous structure increased with increasing Zr content. The crystallization temperature of the Ni–Nb–Zr amorphous alloys decreased with increasing Zr content. The hydrogen flow increased with an increase of the temperature or the difference in the square-roots of hydrogen pressures across the membrane, � ffiffiffi p . At relatively higher temperature up to 673 K or at relatively higher hydrogen pressure difference, � ffiffiffi p up to 550 Pa 1=2 , the hydrogen flow was more strictly
