Two reaction systems that are at first sight very different produce similar macroscopic filamentary product trails. The systems are chemical gardens confined to a Hele-Shaw cell and corroding metal plates that undergo filiform corrosion. We show that the two systems are in fact very much alike. Our experiments and analysis show that filament dynamics obey similar scaling laws in both instances: filament motion is nearly ballistic and fully self-avoiding, which creates self-trapping events.
乍一看截然不同的两个反应系统却产生了相似的宏观丝状产物轨迹。这两个系统分别是限制在赫勒肖盒中的化学花园以及经历丝状腐蚀的金属腐蚀板。我们发现这两个系统实际上非常相似。我们的实验和分析表明，在这两种情况下，细丝动力学都遵循相似的标度律：细丝运动几乎是弹道式的且完全自我避免，这就产生了自陷事件。
