Labyrinth-like Turing patterns are investigated under the influence of an electric field. The patterns form in the ferroin-catalyzed Belousov-Zhabotinsky reaction embedded in the sodium-bis (2-ethylhexyl) sulfosuccinate (AOT) water-in-oil microemulsion. For two different values of the droplet fraction above and below the percolation transition of the system, the electric field induced drift of the patterns is different. Above the percolation transition, a linear increase of the drift velocity with increasing electric field strength is found. However, below the percolation transition, this increase shows an exponential behavior. The patterns are also observed to reorient under high electrical field strength, such that they are arranged perpendicular with respect to the field lines.
在电场影响下对迷宫状图灵模式进行了研究。这些模式形成于嵌入双（2-乙基己基）磺基琥珀酸钠（AOT）油包水微乳液中的亚铁离子催化的贝洛索夫-扎博廷斯基反应中。对于系统渗流转变之上和之下的两种不同液滴分数值，电场引起的模式漂移是不同的。在渗流转变之上，发现漂移速度随电场强度增加呈线性增加。然而，在渗流转变之下，这种增加呈现指数行为。还观察到这些模式在高电场强度下会重新定向，从而使其相对于电场线垂直排列。
