“类流态”是固态合金中存在的一种非线性振荡现象 ,在某些微区表现出明显的流动特性。根据非线性动力学的无标度理论 ,固体类流态“胞”区的天然破裂过程与地壳板块岩石的破裂过程在物理机制和表现形式上具有相似性。通过对固体“类流态”图像灰度值的时间序列进行分析 ,分别用Lyapunov指数和相位随机化方法判定了其混沌特性。研究表明固体“类流态”现象呈现出明显的非线性动力学特征 ,这一研究也为非线性和复杂性研究提供了以材料物理试验为内涵的范例。 “Fluid-like state” is a kind of non-linear oscillatory phenomenon in solid-state alloys, which shows obvious flow characteristics in some micro-regions. According to the non-scale kinetic theory of non-linear dynamics, the natural rupture process of solid “fluid” zone has similarities in physical mechanism and manifestation with that of crustal rock. By analyzing the time series of the gray value of solid “fluid-like” images, the chaotic properties of the solid fluid-like images are evaluated by Lyapunov exponents and phase randomization respectively. The research shows that the solid “fluid-like” phenomenon shows obvious nonlinear dynamic characteristics. This research also provides an example of the material-physical test for the study of nonlinearity and complexity.
