| 摘 要： | 在X射线衍射实验的基础上，把分形理论用于分析In-80wt%Sn在300℃时的液态结构，发现液态结构是一种多度域分形结构，并提出液态结构多度域分形模型.通过分形分析，液态合金的整体结构被清晰地呈现出来.推测多度域两分形之间过渡区的大小和液态合金性质有关，过渡区的变化可能反映了液态合金性质的变化.关键词：液态合金结构分形理论多度域分形

| Abstract: | Based on the results of the X-ray diffraction experiment, we implement the fractal concept to study the liquid structure of In-80wt% Sn at 300℃. Partially-overlapping multirange fractals in the melt In-80wt%Sn are observed. According to the characteristic of the partially-overlapping multirange fractals, a model of multirange fractals in liquid structure is proposed and the simulated results agree with the experimental data, where the relative error is less than 1.5%. From the fractal analysis, the whole structure of liquid is clearly revealed, and the range of the transition region between the fractals is speculated to be related closely with the properties of the liquid alloys，and the changes of the transition region may disclose the changes of the liquid alloy characteristics. |
