论文摘要
从水蒸气中使用精细的，对称模式的冰晶的形成过程通常是复杂的，并且相应的机制仍然不清楚。在这里，我们通过实验构建了一个薄薄的腔室层中的3D管状冰晶体，该室内充满了空气，在冰箱中，摄氏-27摄氏度高。我们在这里还建议从图灵的反应扩散过程的角度研究空心结构的动态形成，并通过冷却空气分子（C-AM）作为激活剂和室 - 室 - 细胞分子（rt-am）（rt-am）（rt-am）（rt-am）（rt-am）进行了由冰晶体组成的3D管状结构的数学建模。模拟产生了一个空心管阵列，该阵列具有相似的几何特征与实验中空心柱的冰晶体结构。该模型提供了在冰晶形成过程中探索图灵不稳定性的可能性。
The process of formation for an ice crystal with elaborate, symmetrical patterns from the water vapor is usually complicated and the corresponding mechanism is still not clear. Here, we experimentally constructed the 3D tubular ice crystals within a thin chamber layer filled with air in a freezer with high humidity at -27 degrees celsius. We here also propose to investigate the dynamic formation of hollow structures from the perspective of Turing's reaction-diffusion process, and a mathematical modelling of the 3D tubular structures composed of ice crystals is conducted by regarding the cooled air molecule (C-AM) as the activator and room-temperature air molecules(RT-AM) as the inhibitor. The simulation generated a hollow tube array that has similar geometric feature with the ice crystal structure of hollow columns in the experiment. This model offers a possibility to explore the Turing instability in the process of ice crystal formation.
