A micro-boat self-propelled by a camphor engine, carrying seed crystals of FeCl, promoted the evolution of chemical gardens when placed on the surface of aqueous solutions of potassium hexacyanoferrate. Inverse chemical gardens (growing from the top downward) were observed. The growth of the "inverse" chemical gardens was slowed down with an increase in the concentration of the potassium hexacyanoferrate. Heliciform precipitates were formed under the self-propulsion of the micro-boat. A phenomenological model, satisfactorily describing the self-locomotion of the camphor-driven micro-boat, is introduced and checked.
用一台由樟脑引擎驱动的微型船，将六氰合铁酸钾溶液表面的 FeCl 种子晶体运移，促进了化学花园的演化。观察到了反向化学花园（从顶部向下生长）。随着六氰合铁酸钾浓度的增加，“反向”化学花园的生长速度减缓。在微型船的自推进作用下形成了螺旋形沉淀物。引入并检查了一个能满意描述樟脑驱动微型船自运动的唯象模型。
