本文简要综述了近年来关于非平衡标度定律的实验研究，重点介绍了理论上已经确定的两种重要的非平凡普适性类：吸收态相变和生长界面。本文首先总结了电驱动湍流液晶的主要结果，这些结果显示了两种湍流状态过渡时定向渗透类的标度规律，以及超临界阶段一种湍流状态侵入另一种湍流状态的卡达-帕里西-张类的标度规律。然后对这些普适性类和相关情况的其他实验研究进行了概述和讨论。并从实际的角度对这些标度律的分析作了评述。
This is a brief survey of recent experimental studies on out-of-equilibrium scaling laws, focusing on two prominent situations where nontrivial universality classes have been identified theoretically: absorbing-state phase transitions and growing interfaces. First the paper summarizes the main results obtained for electrically driven turbulent liquid crystals, which exhibited the scaling laws for the directed percolation class at the transition between two turbulent regimes, and those for the Kardar–Parisi–Zhang class in the supercritical phase where one turbulent regime invades the other. Other experimental investigations on these universality classes and related situations are then overviewed and discussed. Some remarks on analyses of these scaling laws are also given from the practical viewpoint.
