用分形理论探讨了液态In-80%Sn结构及其变化, 证实了液体结构中存在分形结构, 发现随着温度的升高, 与液态合金其它结构参数一样, 分形维数也发生了不连续的变化, 提出分形维数是一个结构敏感参量. 分析认为液态In-Sn合金结构所出现的不连续变化是由于液体中粒子集合体线度减小而出现的线度效应所造成的, 分形维数的突变是温度诱导液态结构不连续的基本特性.
As a new and important problem in condensed state physics, the discontinuous structural change of liquid with temperature rising is testified by various experimental technologies. However, fractal language has been more and more frequently used to describe some disordered physical systems except liquid alloys. This paper has successfully implemented fractal ideas to observe fractal structures in liquid In-Sn alloy and considers its fractal dimension as a physical quantity sensitive to structure. Moreover, from the fractal viewpoint, the mutation of the fractal dimension has indicated once again that the liquid structure change discontinuously with temperature rising.
