| 摘 要： | 本文从计算非晶态材料散射强度的Debye方程,推导出非晶态二元合金模型的Faber-Ziman偏干涉函数计算公式。利用这些公式,计算了Fe83B17和Ni64B36金属玻璃模型的SFeB(Q)和SNiB(Q),并和实验结果及模型计算的偏散射强度IFeB(Q)和INiB(Q)作了比较。文中还计算了Hg2Na液态合金模型的偏干涉函数,并把它们外推到零衍射角时的数值。最后讨论了具有化学短程序合金的全干涉函数在零衍射角附近的行为。关键词：

| Abstract: | The equation of calculating Faber-Ziman partial structure factors for models of binary alloys is derived from Debye equation. The SFeB(Q) and SNiB(Q) of models for Fe83B17 and Ni64B36 metallic glasses are calculated, and compared with the experimental results and the partial scattering intensities IFeB(Q) and INiB(Q) The partial structure factors of model for Hg2Na liquid alloy are also calculated, and extrapolated to the long wavelength limit. Finally, the behavior of the total structure factors near the long wavelength limit for alloys, which have chemical short range order, is discussed. |
