| 摘 要： | 通过对金属间化合物Ａｌ５Ｆｅ２的液态与固态Ｘ射线衍射结果的对比，显示液态及固态结构之间存在密切的相关性。合金熔体Ａｌ５Ｆｅ２中Ｆｅ原子的最近邻均为Ａｌ原子，由此形成的原子团在空间排列成的超结构与Ａｌ５Ｆｅ２的晶体结构相似。

| Abstract: | The close relationship between liquid structure and solid structure of Al 5Fe 2 has been found by a comparision of the results from the X-ray scattering. The nearest neighbours of Fe in the melt Al 5Fe 2 are Al atoms.The superstructure resulted from clusters of Al 5Fe 2 is similar to the solid structure of Al 5Fe 2. |
